You need to run build with JDK or have tools.jar on the classpath.If this occures during eclipse build make sure you run eclipse under JDK as well (com.mysema.maven:apt-maven-plugin:1.1.3: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:JavaJDKjdk1.8.0_20

CLASSPATH      ：    .;%JAVA_HOME%libdt.jar;%JAVA_HOME%lib ools.jar;

Path                   ：    %JAVA_HOME%jrein

2.改为jdk

3.在eclipse.ini文件新增jdk的javaw.exe配置

4.重启eclipse ok 亲测可用

自己确实用这种方法解决了，第三步中的javaw.exe不能少
