导入的maven项目不会显示为java项目。显示文件夹 [英] imported maven project does not appear as java project. Shows folders

问题描述

我将现有项目源代码从SVN检出到系统中的文件夹。
然后我打开eclipse。导入项目 - >现有的Maven项目。

导入时没有问题。但是，Project Explorer将其显示为只是文件夹而不是包。 （就像我们创建一个包，然后添加类，它显示一个不同的图标为包root）。我也打开了Navigator和Package Explorer。但是他们也将它们显示为文件夹。

我试过：

  mvn eclipse：clean 
 mvn eclipse：eclipse 
  

在项目的根目录。但是这没有帮助。

任何人都可以帮助这个？

我的文件夹结构：

  ecs-> 
 ecs-ejb-> 
 src / java / main / com / xxx 
 pom.xml 
 ecs-> ear-> 
 src / java / main / com / xxx 
 pom.xml 
 pom.xml 
  

解决方案

尝试：

1. 右键单击项目 - >配置 - >转换为Maven项目

----编辑----

如果这不起作用，有可能有人将他们的环境文件检入SVN。如果他们签到：

• .project


• .classpath

它们可能与您的环境（eclipse的不同设置/插件/版本...）冲突。尝试删除您的项目，删除文件夹/文件，然后从SVN中删除这些文件，并重复您的初始过程。所有这些文件/文件夹将在导入eclipse时生成。




----编辑2 ----





根据您最近编辑的问题，您有一个多模块项目。如果您只在父项目上执行此操作，则不存在源文件夹。所以你不会看到它。您应该：



1. 文件 - >导入...


2. 选择现有的Maven项目， / li>
   
3. 将根目录设置为ecs / ecs-ejb，完成


4. 对所有其他模块重复。



在eclipse中，多模块maven项目的每个模块都需要自己的eclipse项目。




I checked out the existing project source code from SVN to a folder in my system. Then I opened eclipse. Import Project-> Existing Maven Project.

It imported without issues. However, Project Explorer shows it as just folders instead of packages. (Like when we create a package and then add classes to it, it shows a different icon for package root). I opened Navigator and Package Explorer as well. But they are showing them as folders as well.

I tried:

mvn eclipse:clean
mvn eclipse:eclipse

on the root of the project. But it did not help.

Can anyone help on this one?

My folder structure:

ecs->
     ecs-ejb->
        src/java/main/com/xxx
        pom.xml
     ecs->ear->
        src/java/main/com/xxx
        pom.xml
     pom.xml

解决方案

Try to:

1. Right click the project->Configure->Convert to Maven Project

---- Edit ----

If this doesnt work, it is likely that someone checked in their environment files into your SVN. If they checked in:

• .project
• .classpath
• .settings/

They could be conflicting with your environment (different settings/plugins/versions of eclipse...). Try dropping your project, deleting the folder/files, then remove these files from SVN, and repeat your initial process. All of these files/folders will get generated during the import to eclipse.

---- Edit 2 ----

Per your recent edit to the question, you have a multi-module project. If you only did this on the parent project, then there is no source folder. So you wouldn't see it. You should:

1. File->Import...
2. Choose Existing Maven Projects, Next
3. Set the Root Directory to ecs/ecs-ejb, Finish
4. Repeat for all other modules.

In eclipse, each module of a multi-module maven project needs its own eclipse project.
