maven build An unknown compilation problem occurred

项目在开发环境下使用maven clean package 是成功的，

在jenkins下进行build就是失败的。

其中主要的失败日志就是：

Error org.apache.maven.cli.MavenCli - Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project china-great: Compilation failure

Error org.apache.maven.cli.MavenCli - An unknown compilation problem occurred

Error org.apache.maven.cli.MavenCli - -> [Help 1]

但是这些异常日志其实是没有太大用处的。

还好，我继续往上面翻日志的时候，发现了一个宝藏，正式这个宝藏帮助我找到了解决的办法

Fatal Error: Unable to find package java.lang in classpath or bootclasspath

然后可以看到pom.xml中定义了

   

        ${JAVA_HOME}/jre/lib/rt.jar;${JAVA_HOME}/jre/lib/jce.jar

   

里面的;在windows下面是没有问题的，但是在linux下面是有问题的，

请参考：

中的

Override the char used between path folders. The system-dependent path-separator character. This field is initialized to contain the first character of the value of the system property path.separator. This character is used to separate filenames in a sequence of files given as a path list. On UNIX systems, this character is ':'; on Microsoft Windows systems it is ';'.

User property is: mdep.pathSeparator.

好的，那我们就将;修改为${path.separator}，问题解决。
