Jenkins waitForAsynchronousExecutions 问题排查

JavaWeb开发项目少不了Jenkins的使用

Jenkins 配合shell 脚本可以方便的做到持续化集成，一般也就是tomcat 挂了 打不开，使用时间长了 硬盘空间不足
平时注意合理配置项目，经常维护就可以解决

Jenkins 虽然功能强大，但免不了自身会有bug

罕见的问题：

日志分析

• 项目明显已经打包编译完成 install 到本地
  实际上不影响测试，对于jenkins 构建项目是失败的,导致后续的构建无法运行
  整个项目打包编译不成功

• jenkin 自身报错
  日志本身没有什么有价值的信息
  仅能确定jenkins 自身报错

定位关键信息：

hudson.maven.AbstractMavenBuilder.waitForAsynchronousExecutions(AbstractMavenBuilder.java:186)

查找资料：

确定解决方案：

删除 .jenkins/fingerprints/ 目录下所有文件夹

重启jenkins

问题解决
