Question

我刚收到一个项目要处理，我正在尝试运行“mvn clean install”以便安装所有插件和依赖项，我收到此错误。有任何想法吗？

org.apache.maven.lifecycle.LifecycleExecutionException：无法在项目EHS_ITO_BACKEND上执行目标org.apache.maven.plugins：maven-compiler-plugin：3.1：compile（default-compile）：编译失败此环境中未提供编译器。也许你是在运行JRE而不是JDK？

Answer 1

Maven需要一个JDK来编译你的项目。 Maven使用JAVA_HOME根据此消息找到JDK ......

编译失败此环境中未提供编译器。也许你是在运行JRE而不是JDK？

...您的JAVA_HOME不存在或者没有指向JDK。

如果你运行mvn -version它将告诉你它用于Java的用途。你应该看到这样的东西：

Java version: 1.8.0_51, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home/jre

如果你没有看到，那么你必须设置你的JAVA_HOME。来自the docs：

在Unix上：

export JAVA_HOME=jdk-install-dir

在Windows上

Right click My Computer and select Properties.

On the Advanced tab, select Environment Variables, and then edit JAVA_HOME to point to where the JDK software is located, for example, C:\Program Files\Java\jdk1.6.0_02.
