IDEA报错Error:Cannot build artifact ‘a (1):war exploded‘ because it is included into a circular depend

IDEA报错

Error:Cannot build artifact 'a (1):war exploded' because it is included into a circular dependency (artifact 'a (1):war exploded', artifact 'a:war exploded')

原因，切换分支生成war包生成多了，移除掉多的war包即可

解决方法

File-->Structure

找到Artifacts 移除掉多余war或者war exploded即可。
