此问题一般发生在Myeclipse 保存文件并自动部署时候。
Errors occurred during the build.
Errors running builder 'DeploymentBuilder' on project '项目名'.
java.lang.NullPointerException
有一种产生此错误的原因是因为此项目不不是由myeclipse创建的。
所以你需要检查.project 文件。
并且添加com.genuitec.eclipse.j2eedt.core.webnature
1、首先关闭MyEclipse工作空间。
2、然后删除工作空间下的
“/.metadata/.plugins/org.eclipse.core.runtime/.settings/com.genuitec.eclipse.ast.deploy.core.prefs”
取消myeclipse的自动部署:
右键点击项目 ->properties -> Builders ,将DeploymentBuilder勾选去除.
