为什么Maven的mvn clean第一次无法使用? [英] Why doesn't Maven's mvn clean ever work the first time?

问题描述

十分之九.我必须多次执行 mvn clean ，直到构建错误消失为止.还有其他人会遇到吗?有什么办法可以在Maven中解决此问题?如果没有，您如何解决?我写了一个bat文件，该文件删除了目标文件夹，并且效果很好，但是当您处理多个项目时，这是不切实际的.我正在使用Maven 2.2.1.

Nine times out of ten when I run mvn clean on my projects I experience a build error. I have to execute mvn clean multiple times until the build error goes away. Does anyone else experience this? Is there any way to fix this within Maven? If not, how do you get around it? I wrote a bat file that deletes the target folders and that works well, but it's not practical when you are working on multiple projects. I am using Maven 2.2.1.

推荐答案

可能是您的IDE或其他进程正在按住目标"文件夹并阻止maven删除它.

It may be that your IDE or some other process is holding on to the the "target" folder and preventing maven from deleting it.
