you run eclipse under JDK as well (com.mysema.maven:apt-maven-plugin:1.1.1:process:default:generate-sources)

1.仔细的看看自己的电脑的环境变量有没有配置错误，我的电脑是这样配置的：
JAVA_HOME ： C:\JavaJDK\jdk1.8.0_20
Path ： %JAVA_HOME%\jre\bin;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;
2.检查Eclipse中jre是都配置正确
3.在eclipse.ini文件新增jdk的javaw.exe配置
4.重启eclipse ok 亲测可用
