m2eclipse：多模块和父构建异常
我是 m2eclipse 的新手，我创建了一个虚拟 java 项目（mytest4）并选中启用依赖项管理，之后，该插件创建了一个 pom.xml 文件。我手动向虚拟项目添加了parent信息，例如groupId、artifactId和version等。然后我将模块添加到父项目中，父项目 projectType 是 pom 而不是 jar。但是，当我使用clean install进行构建时，出现错误：
[DEBUG] Extension realms for project com.multimod:myproject:pom:0.0.1-SNAPSHOT: (none)
[DEBUG] Looking up lifecyle mappings for packaging pom from ClassRealm[plexus.core, parent: null]
[ERROR] The build could not read 1 project ->
[Help 1]org.apache.maven.project.ProjectBuildingException: Some problems were encountered while processing the POMs:
[ERROR] Child module C:\workspace\myproject\mytest4 of C:\workspace\myproject\pom.xml does not exist @
[ERROR] The project com.multimod:myproject:0.0.1-SNAPSHOT(C:\workspace\myproject\pom.xml) has 1 error
[ERROR] Child module C:\workspace\myproject\mytest4 of C:\workspace\myproject\pom.xml does not exist
我不明白C:\workspance\myproject\pom.xml不存在。
你能给一些提示吗？ 谢谢。
I am new to m2eclipse, and I created a dummy java project (mytest4) and checked enable dependency management, after that, the plugin created a pom.xml file. I manually added parent information, such as groupId, artifactId and version, etc. to the dummy project. Then I added modules to the parent project, and the parent projectType is pom not jar. However, when I build using clean install, I get an error:
[DEBUG] Extension realms for project com.multimod:myproject:pom:0.0.1-SNAPSHOT: (none)
[DEBUG] Looking up lifecyle mappings for packaging pom from ClassRealm[plexus.core, parent: null]
[ERROR] The build could not read 1 project ->
[Help 1]org.apache.maven.project.ProjectBuildingException: Some problems were encountered while processing the POMs:
[ERROR] Child module C:\workspace\myproject\mytest4 of C:\workspace\myproject\pom.xml does not exist @

[ERROR] Child module C:\workspace\myproject\mytest4 of C:\workspace\myproject\pom.xml does not exist
I don't understand C:\workspance\myproject\pom.xml does not exist.
Could you give some hints?
Thank you.

您可能必须在 mytest4 pom 文件中设置父 pom 文件的相对路径。默认值为
../pom.xml，因此您的路径为C:\workspace\myproject\pom.xml。至于你在评论中的子问题。右键单击项目并选择

../pom.xmlhence your pathC:\workspace\myproject\pom.xml.As to your sub question in the comment. Right click on the project en select
