Errors occurred during the build.

Errors occurred during the build. 编译时经常出现： Errors occurred during the build. Errors running builder 'JavaScript Validator' on project 'XXXXX'. java.lang.NullPointerException 这个主要是JS的校验比较纠结，经常导致编译出错，这时把JavaScript Validator去掉即可。 解决方案: 选择项目--右键Properties--Builders--如果有则取消第一项“JavaScript Validator”的复选框即可。
