Question

我正在尝试在shell脚本中执行maven构建。我在ec2实例中在Amazon Linux上运行。

以下是我脚本中的前两行：

sudo git clone [url of git repository]

sudo mvn clean package -f /path/to/pom.xml

如果我在命令行中单独输入它们，那么它可以工作。

如果我已经克隆了存储库然后执行脚本，那么它可以工作。它跳过克隆存储库（因为它已经存在）并继续执行脚本的其余部分。再次，这是有效的。

当repo不存在且我运行脚本时会出现问题。它克隆远程仓库并且看起来是成功的。

但是当它试图打包项目时我遇到了这个错误：

您可以看到克隆了repo，然后构建启动，但失败了。我甚至尝试在clone和mvn package命令之间等待5秒。

Answer 1

错误清楚地表明这是权限问题：

Cannot create resource output directory: /home/ec2-user/devops/UserRegistrationClient/target/classes

这与您的描述“The problem occurs when the repo isn't present and I run the script”一致，因为当它不存在时，您使用sudo创建它，因此它属于root，而权限不会更改回购已经存在。

为了更好地了解实际情况，您应该在脚本中添加一些跟踪，特别是一些ls -l，以便检查您操作的目录的所有者，以及一些whoami为了看谁在执行某项行动

Maven - 无法在shell脚本中创建资源输出目录
