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

解决方法1：

Go into Window > Preferences > Java > Installed JREs > and check your installed JREs. You should have an entry with a JDK there.
解决方法2：
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
%JAVA_HOME%injavaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xms40m
-Xmx512m
