Question

我在我的项目上运行了mvn clean install命令，我收到了以下错误。这是一个java web项目。你能告诉我这个问题的原因是什么吗？提前致谢

下面是我的pom.xml

Answer 1

如异常中所述，maven无法创建目录。尝试手动创建此目录以确保路径有效并且您有足够的权限。

Answer 2

在Windows上，无法创建文件夹的原因是：

其他一些进程正在同时删除此文件夹您无权访问此文件夹该文件夹位于网络共享上在Windows上，网络共享是出了名的不可靠。不要将它们用于任何自动化任务。始终使用驻留在本地硬盘上的所有文件构建项目。

如果您同时使用Maven和Eclipse进行构建，则应将它们配置为使用不同的目标文件夹。见https://stackoverflow.com/a/54366009/34088

你的POM应该是这样的：

<project>
 ...

<build>
<outputDirectory>${basedir}/${target.dir}/classes</outputDirectory>
<testOutputDirectory>${basedir}/${target.dir}/test-
classes</testOutputDirectory>
</build>

<properties>
<target.dir>target</target.dir>
</properties>

<profiles>
<profile>
  <id>eclipse-folders</id>
  <properties>
    <target.dir>target-eclipse</target.dir>
  </properties>
 </profile>
  </profiles>

...

剩下的就是在IDE中启用配置文件eclipse-folders。

Answer 3

这里有两个问题。

其他一些进程可能会在您运行mvn
您没有足够的权限将数据写入C:\GIT_REPOSITORIES\目录。

如果您具有管理员权限，则可以从cmd提示符作为管理员运行mvn clean install。否则，获得足够的权限将数据写入上述目录。

希望这有帮助！
