关于Saiku的二次开发，在本地编译然后启动自己编译好的Saiku服务
Saiku是开源的，从github上能下载源代码，本例中的saiku源码也是从github上找的，然后自己改了一些pom.xml，以及其它调整。
当前提供的saiku版本为 3.9
一、Saiku源码下载
下载saiku源码地址： https://github.com/DFX339/saiku-3.9.git #这是我改好在本地编译通过的saiku源码
二、Saiku相关jar包下载
在本地编译时需要注意有些jar包可能从仓库中获取不到，需要手动将缺失的jar包copy到本地maven仓库对应下载不下来jar包的目录下
这里将一些比较难找的jar包上传到了github上
saiku的jar包 github 地址： https://github.com/DFX339/saiku-repository.git
获取其他下载不下来jar的方式：
1. 下载最新版本的saiku-server ,从saiku-server\tomcat\webapps\saiku\WEB-INF\lib 目录下对应的jar包，copy到本地maven仓库目录
2. 从 https://nexus.pentaho.org/#browse/search 中搜索jar包，下载下来然后copy到本地maven仓库目录
maven的配置文件：
本机存放目录： D:\Program Files\apache-maven-3.5.3\conf\settings - saiku.xml
setting-saiku.xml 文件内容：

--><!--| This is the configuration file for Maven. It can be specified at two levels:|| 1. User Level. This settings.xml file provides configuration for a single user,| and is normally provided in ${user.home}/.m2/settings.xml.|| NOTE: This location can be overridden with the CLI option:|| -s /path/to/user/settings.xml|| 2. Global Level. This settings.xml file provides configuration for all Maven| users on a machine (assuming they're all using the same Maven| installation). It's normally provided in| ${maven.home}/conf/settings.xml.|| NOTE: This location can be overridden with the CLI option:|| -gs /path/to/global/settings.xml|| The sections in this sample file are intended to give you a running start at| getting the most out of your Maven installation. Where appropriate, the default| values (values used when the setting is not specified) are provided.||-->

If set to false,| maven will use a sensible default value, perhaps based on some other setting, for| the parameter in question.|| Default: true<interactiveMode>true</interactiveMode>--><!-- offline| Determines whether maven should attempt to connect to the network when executing a build.| This will have an effect on artifact downloads, artifact deployment, and others.|| Default: false<offline>false</offline>--><!-- pluginGroups| This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e.| when invoking a command line like "mvn prefix:goal". Maven will automatically add the group identifiers| "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list.|--><pluginGroups><!-- pluginGroup| Specifies a further group identifier to use for plugin lookup.<pluginGroup>com.your.plugins</pluginGroup>--><pluginGroup>org.mortbay.jetty</pluginGroup><pluginGroup>org.jenkins-ci.tools</pluginGroup></pluginGroups><!-- proxies| This is a list of proxies which can be used on this machine to connect to the network.| Unless otherwise specified (by system property or command-line switch), the first proxy| specification in this list marked as active will be used.|--><proxies><!-- proxy| Specification for one proxy, to be used in connecting to the network.|<proxy><id>optional</id><active>true</active><protocol>http</protocol><username>proxyuser</username><password>proxypass</password><host>proxy.host.net</host><port>80</port><nonProxyHosts>local.net|some.host.com</nonProxyHosts></proxy>--></proxies><!-- servers| This is a list of authentication profiles, keyed by the server-id used within the system.| Authentication profiles can be used whenever maven must make a connection to a remote server.|--><servers><!-- server| Specifies the authentication information to use when connecting to a particular server, identified by| a unique name within the system (referred to by the 'id' attribute below).|| NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are| used together.|--><server><id>onelife-snapshorts</id><username>deployment</username><password>Abcd1234</password></server><!-- Another sample, using keys to authenticate.<server><id>siteServer</id><privateKey>/path/to/private/key</privateKey><passphrase>optional; leave empty if not used.</passphrase></server>--></servers><!-- mirrors| This is a list of mirrors to be used in downloading artifacts from remote repositories.|| It works like this: a POM may declare a repository to use in resolving certain artifacts.| However, this repository may have problems with heavy traffic at times, so people have mirrored| it to several places.|| That repository definition will have a unique id, so we can create a mirror reference for that| repository, to be used as an alternate download site. The mirror site will be the preferred| server for that repository.|--><mirrors><!-- mirror| Specifies a repository mirror site to use instead of a given repository. The repository that| this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used| for inheritance and direct lookup purposes, and must be unique across the set of mirrors.|<mirror><id>onelife-mirrorId</id><mirrorOf>onelife-public-repositories,central</mirrorOf><name>onelife Name for this Mirror.</name><url>http://10.6.0.118:8080/nexus/content/groups/onelife-public-repositories/</url></mirror>--><mirror><id>nexus-aliyun</id><mirrorOf>*,!jeecg,!jeecg-snapshots, !pentaho</mirrorOf> <name>Nexus aliyun</name><url>https://maven.aliyun.com/repository/public</url></mirror></mirrors><!-- profiles| This is a list of profiles which can be activated in a variety of ways, and which can modify| the build process. Profiles provided in the settings.xml are intended to provide local machine-| specific paths and repository locations which allow the build to work in the local environment.|| For example, if you have an integration testing plugin - like cactus - that needs to know where| your Tomcat instance is installed, you can provide a variable here such that the variable is| dereferenced during the build process to configure the cactus plugin.|| As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles| section of this document (settings.xml) - will be discussed later. Another way essentially| relies on the detection of a system property, either matching a particular value for the property,| or merely testing its existence. Profiles can also be activated by JDK version prefix, where a| value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.| Finally, the list of active profiles can be specified directly from the command line.|| NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact| repositories, plugin repositories, and free-form properties to be used as configuration| variables for plugins in the POM.||--><profiles><!-- profile| Specifies a set of introductions to the build process, to be activated using one or more of the| mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>| or the command line, profiles have to have an ID that is unique.|| An encouraged best practice for profile identification is to use a consistent naming convention| for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.| This will make it more intuitive to understand what the set of introduced profiles is attempting| to accomplish, particularly when you only have a list of profile id's for debug.|| This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.<profile><id>jdk-1.4</id><activation><jdk>1.4</jdk></activation><repositories><repository><id>jdk14</id><name>Repository for JDK 1.4 builds</name><url>http://www.myhost.com/maven/jdk14</url><layout>default</layout><snapshotPolicy>always</snapshotPolicy></repository></repositories></profile>--><!--| Here is another profile, activated by the system property 'target-env' with a value of 'dev',| which provides a specific path to the Tomcat instance. To use this, your plugin configuration| might hypothetically look like:|| ...| <plugin>| <groupId>org.myco.myplugins</groupId>| <artifactId>myplugin</artifactId>|| <configuration>| <tomcatLocation>${tomcatPath}</tomcatLocation>| </configuration>| </plugin>| ...|| NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to| anything, you could just leave off the <value/> inside the activation-property.|<profile><id>env-dev</id><activation><property><name>target-env</name><value>dev</value></property></activation><properties><tomcatPath>/path/to/tomcat/instance</tomcatPath></properties></profile>--><profile><id>saiku-profile</id><activation><activeByDefault>false</activeByDefault><jdk>1.8</jdk></activation><repositories><repository><id>Analytical Labs Repo</id><name>Analytical Labs Repo-releases</name><url>http://repo.meteorite.bi/content/repositories/alabs-release-local/</url></repository><repository><id>Analytical Labs snapshots</id><name>Analytical Labs Repo-releases</name><url>http://repo.meteorite.bi/content/repositories/alabs-snapshot-local/</url></repository><repository><id>pentaho-third-party</id><url>http://nexus.pentaho.org/content/repositories/proxied-3rd-party-releases/</url></repository><repository><id>pentaho-public-release</id><url>http://nexus.pentaho.org/content/repositories/pentaho-public-release-repos/</url></repository><repository><id>pentaho-snapshot</id><url>http://nexus.pentaho.org/content/repositories/public-snapshots/</url></repository> <repository><id>central</id><name>Maven Repository Switchboard</name><layout>default</layout><url>https://maven.aliyun.com/repository/public</url><snapshots><enabled>false</enabled></snapshots></repository><repository><id>apache</id><name>Apache repo</name><layout>default</layout><url>https://repository.apache.org/content/repositories/snapshots/</url><snapshots><enabled>true</enabled></snapshots></repository><repository><id>nuxeo</id><url>https://maven-us.nuxeo.org/nexus/content/repositories/public-snapshot/</url></repository><repository><id>nuxeo_thirdparty</id><url>https://maven-us.nuxeo.org/nexus/content/repositories/thirdparty-snapshots/</url><snapshots><enabled>true</enabled></snapshots></repository><repository><id>jboss</id><url>http://repository.jboss.org/nexus/content/groups/public/</url></repository><repository><id>atlassian</id><name>Atlassian Public</name><layout>default</layout><url>https://maven.atlassian.com/content/repositories/atlassian-public</url><snapshots><enabled>true</enabled></snapshots></repository><repository><id>ApacheSnapshot</id><name>Apache Repository</name><url>https://repository.apache.org/content/groups/snapshots/</url><snapshots><enabled>true</enabled></snapshots></repository><repository><id>osc</id><url>https://maven.aliyun.com/repository/public/</url></repository><repository><id>osc_thirdparty</id><url>https://maven.aliyun.com/repository/public/</url></repository></repositories><pluginRepositories><pluginRepository><id>Analytical Labs Plugin Repo</id><name>Analytical Labs Repo-releases</name><url>http://repo.meteorite.bi/content/repositories/alabs-release-local/</url></pluginRepository><pluginRepository><id>osc_plugin</id><url>https://maven.aliyun.com/repository/public/</url></pluginRepository></pluginRepositories></profile> </profiles><activeProfiles><!-- <activeProfile>onelife-profile</activeProfile> --><activeProfile>saiku-profile</activeProfile></activeProfiles><!-- activeProfiles| List of profiles that are active for all builds.|<activeProfiles><activeProfile>alwaysActiveProfile</activeProfile><activeProfile>anotherAlwaysActiveProfile</activeProfile></activeProfiles>-->

三、Saiku本地编译
1. 下载saiku源码
2. 将缺失的jar包引入 (下载相关jar包手动复制到maven仓库对应jar存放目录中，然后再Eclipse上更新maven: maven --》 update project 记得勾选offline )
3. 先执行maven命令：
1. mvn clean install 编译 saiku-olap-util ,
2. mvn clean install 编译 saiku-core,
3. 再在父pom上编译整个项目 mvn clean install
四、使用本地编译好的Saiku服务
编译通过后，在Saiku-server 项目下，会生成target目录信息，saiku服务就在 saiku-release-3.90\saiku-server\target\dist\saiku-server 目录下
按照之前的安装saiku的方法，直接双击start-saiku.bat 即可在windows上启动本地编译的saiku.
后续步骤就是上传license信息等使用saiku的相关步骤了，详情请参考关于Saiku的下载与安装博客一： https://www.cnblogs.com/DFX339/p/10253186.html
Problem:
1、 如果出现问题： Plugin Execution not covered by lifecycle configuration
Maven项目POM文件错误，提示“Plugin execution not covered by lifecycle configuration”的解决方案
