Jenkins protoc: command not found

个人博客地址：Jenkins protoc: command not found | 一张假钞的真实世界

在使用Jenkins编译Hadoop3.1.2时报错信息如下：

[INFO] --- hadoop-maven-plugins:3.1.2:protoc (compile-protoc) @ hadoop-common ---
[WARNING] [protoc, --version] failed: java.io.IOException: Cannot run program "protoc": error=13, 权限不够
[ERROR] stdout: []
[INFO] ------------------------------------------------------------------------

原因是Jenkins中找不到protoc命令。解决方法是在Jenkins中配置环境变量PATH指定protoc路径。

再次执行发现以下错误：

protoc: error while loading shared libraries: libprotobuf.so.8: cannot open shared object file: No such file or directory

解决方法跟PATH配置一样道理，配置一个新的环境变量LD_LIBRARY_PATH：
