No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

使用m2eclipse可能遇到如下错误
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project hello-world: Compilation failure

这是因为Eclipse默认是运行在JRE上的,而m2eclipse的一些功能要求使用JDK。解决方法是配置Eclipse安装目录的eclipse.ini文件,在-vmargs 参数的前面,添加vm配置指向JDK。例如:

--launcher.appendVmargs
-vm
C:\Program Files\Java\jdk1.7.0_21\bin\javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xms40m
-Xmx512m
