最近在使用Extjs 在springsource Tool Suite运行时老是出现：
Errors occurred during the build.
Errors running builder 'JavaScript Validator' on project test.
java.lang.NullPointerException
解决方案：要就把JavaScript Validator去掉。方法是：选择项目—-右键Properties—-Builders(排二个)—-点一下右则会有四项—-取消第一项“JavaScript Validator”的勾就行了

今天eclipse一直提示
Errors occurred during the build.
但是项目可以启动不受影响 最后解决问题的方法是
将builder中的javascript validator 取消勾选
