我已将maven添加到我的路径中。当我运行命令mvn -v时，它返回：

Apache Maven 3.5.2 (138edd61fd100ec658bfa2d307c43b76940a5d7d; 2017-10-18T10:58:13+03:00) 
Maven home: /Users/yarkoni/apache-maven-3.5.2 Java version: 9, vendor: Oracle Corporation 
Java home: /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home 
Default locale: en_US, platform encoding: UTF-8 OS name: "mac os x", 
version: "10.12.6", arch: "x86_64", family: "mac"

据我所知，为了安装我下载并将其添加到我的PATH。 然后我尝试在本地试用他的appEngine app示例：

mvn -Plocal clean appengine:devserver

我收到以下错误：

2 个答案:

答案 0 :(得分：0)

 java.nio.file.NotDirectoryException: /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/lib/modules

似乎/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/lib/modules不是当前文件系统中的目录，但它应该是。也许某人或某事与您的Java安装有关。您应该确保此路径指向目录或重新安装JDK。

答案 1 :(得分：0)

查看this。似乎maven编译器可以与不同的编译器（例如，容易出错的，plexus等）一起使用，并且这些插件在JDK开发中略有落后。

您有2个选择：

  • 使用JDK 8进行构建
  • 找出所需的配置（例如error prone）

希望这对某人有帮助，我仍在调查自己哪种方法更合适。

编辑：我暂时降级了，但是我打算进行调查，一旦完成，我将更新此答案。
