springboot项目maven打包报java.lang.OutOfMemoryError: GC overhead limit exceeded

springboot项目打war包时报GC
操作就是package，下图

我的解决方法：
添加JVM参数

  1. -XX:-UseGCOverheadLimit，无效
  2. 设置-Xmx到4096m也没有用，下图：

这是-Xmx4096m时的报错信息，如下：

系统资源不足。

请开发、架构师进行指导！感谢！

我看你是在idea里打包的吧，估计是idea默认的内存不足。可以在 菜单的 Help》》Change Memory Setting 里把idea内存设置大些。

调整完重启idea再试试

内存满了，关掉一些java进程（项目）。
