Maven 为 JDK9 做好准备了吗? [英] Is Maven ready for JDK9?

问题描述

今天我尝试了 最新的 jdk9 Build 113 并尝试编译 我的项目 使用最新的 Maven 3.3.9

Today I tried the latest jdk9 Build 113 and tried to compile my project with the latest Maven 3.3.9

这些是命令(部分通过twitter找到)

These are the commands (found partially via twitter)

export MVN_OPTS="-Dmaven.compiler.fork -Dmaven.compiler.executable=/somewhere/Downloads/jdk-9/bin/javac"
export JAVA_HOME="/somewhere/Downloads/jdk-9"
mvn clean install

但我得到这个错误 ...简而言之:

But I get this error ... in short:

JDK9 使用的正确 maven 配置或参数是什么?

$ mvn --version
