maven 无法在 minty 下运行

maven 无法在 minty 下运行

我正在运行 Windows 7 和 cygwin（最新）

当我使用 cygwin 基本控制台时，maven 运行良好

当我打开 mintty 并运行 mvn 时，出现此异常

$ mvn --version
java.lang.NoClassDefFoundError: org/codehaus/plexus/classworlds/launcher/Launcher
Caused by: java.lang.ClassNotFoundException: org.codehaus.plexus.classworlds.launcher.Launcher

        at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: org.codehaus.plexus.classworlds.launcher.Launcher.  Program will exit.

我没看到任何不同。这是我的环境

我通常会开始从 java_home 和 classpath 进行挖掘，但它在 cygwin 的基本 shell 下运行的事实让我很难受。

答案1

您应该检查 JAVA_HOME、CLASSPATH 以及 java 可能关心的其他环境部分。控制台和 mintty 中的环境不一定相同，因为例如控制台通常通过 Cygwin.bat 调用，而 mintty 则不是，因此如果您在 Cygwin.bat 中设置了某些内容，它将不会显示在 mintty 会话中。
