${project.basedir}/../
However, access resources in a different module is something I try to avoid. I'd suggest using the unpack goal of the maven-dependency-plugin.
但是，我尽量避免访问不同模块中的资源。我建议使用maven-dependency-plugin的解包目标。

Please, don't try to go outside the basedir, because it's considered a very bad practice.
Even if you succeed now, it will be the start of a workaround over workaround, trying to battle Maven. In the end, Maven will win.
If a developer checks out a directory with a pom.xml, it should be able run the project with mvn verifywithout any references to other directories.
请不要试图走出 basedir，因为这被认为是一种非常糟糕的做法。即使你现在成功了，这也将是一种替代变通方法的开始，试图与 Maven 抗争。最终，Maven 将获胜。如果开发人员签出带有 的目录pom.xml，它应该能够在mvn verify不引用其他目录的情况下运行项目。
If these are shared resources, make it a separate project and include it as a dependency (search for multi module projects). Or use the maven-remote-resources-pluginto pull these resources into your project.
如果这些是共享资源，请将其设为单独的项目并将其作为依赖项包含（搜索多模块项目）。或者使用maven-remote-resources-plugin将这些资源拉入您的项目。

I had the requirement of moving zip generated in MainDirectory/Submodule/target/ to MainDirectory/target/. I tried all solutions from everywhere but I was unable to solve. I finally tried Ant plugin in pom.xml of submodule to copy as below:
我需要将 MainDirectory/Submodule/target/ 中生成的 zip 移动到 MainDirectory/target/。我尝试了所有地方的所有解决方案，但我无法解决。我终于在子模块的 pom.xml 中尝试了 Ant 插件复制如下：
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-antrun-plugin</artifactId> <version>1.7</version> <executions> <execution> <id>copy to parent target</id> <phase>package</phase> <goals> <goal>run</goal> </goals> <configuration> <target> <copy todir="../target/" overwrite="true" flatten="true"> <fileset dir="${basedir}/target/"/> </copy> </target> </configuration> </execution> </executions> </plugin>
