执行maven时出现Javaclasses.jar'could not find错误

Question

我刚刚在 Mac El Captain 上安装了 java 8 和 maven。我已正确设置所有环境变量，并且 java -version 确实显示了 java 版本。但是当我尝试从终端运行 Maven 时，出现以下错误:

File or url '/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Classes/classes.jar' could not be found
java.net.MalformedURLException: no protocol: /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Classes/classes.jar
    at java.net.URL.<init>(URL.java:593)

    at com.werken.forehead.Forehead.config(Forehead.java:131)
    at com.werken.forehead.Forehead.main(Forehead.java:579)

有什么想法吗？

Answer 1

对于 Maven 1.x，我发现以下 bin/maven shell 脚本在 Mac 上对我造成了同样的错误:

if $darwin; then
    TOOLS_JAR="/System/Library/Frameworks/JavaVM.framework/Versions/${JAVA_VERSION}/Classes/classes.jar"
fi

我只是编辑了 bin/maven 脚本文件并注释掉了 if $darwin; then ... fi 部分，现在可以正常工作了。
