本文记录了 ranger2.1版本的编译过程，与遇到的一些bug的解决方法。
准备
1 外部工具依赖
需要linux环境，保证python命令可用，如果只装了python3，推荐
apt install -y python-is-python3
另外还需要安装gcc
apt install gcc -y
2 排除kylin模块
kylin2.6.4依赖calcite-linq4j-1.16.0-kylin-r2
这个jar包在外部maven仓库是找不到的，导致build失败，参考：
https://issues.apache.org/jira/browse/RANGER-2994
https://issues.apache.org/jira/browse/RANGER-2999
因为是kylin本身的依赖问题，不是ranger的锅，这里谴责一下kylin然后对其选择性放弃
放弃方法：在pom.xml将其所有的module注释掉，如下
<!-- <module>plugin-kylin</module>-->
<!-- <module>ranger-kylin-plugin-shim</module>-->
3 ranger-examples-distro错误
参考：https://github.com/apache/ranger/pull/71
根据issue，修改 sampleapp.xml 和 plugin-sampleapp.xml
4 ranger client
官方的rangerClient有bug，新版本已修复，但还没发布，需要自行编译
步骤：
- 参考官方仓库 ranger/intg/src/main/java 工程，可直接搬运过来，原来的目录要先删掉
- 将 ranger/intg/pom.xml 中 ranger-plugins-common 的版本从$ 改为2.1.0（即公网仓库能找到的最新版本）
执行编译
1 编译各个组件 tar.gz包
在ranger工程下执行，执行成功可以在target下看到包
mvn clean compile package assembly:assembly -DskipTests -DskipJSTests -Dpmd.skip=true
