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。
