无法从 Eclipse Luna 中的原型创建项目

Question

I am trying to create a simple Maven project in Eclipse Luna. As this is my first maven project so I am starting with a simple one. I am trying to crate a simple web project using the webapp-j2ee14 archetype.

While creating I found that this archetype is not present in archetype list. So I tried with Add Archetype option and Provided the following archetype options.

<archetype>
  <groupId>org.codehaus.mojo.archetypes</groupId>
  <artifactId>webapp-j2ee14</artifactId>
  <version>1.3</version>
  <repository>http://repo1.maven.org/maven2/org/codehaus/mojo/archetypes/webapp-j2ee14/1.3/</repository>
</archetype>

The above code snippet is basically from archetype-catalog.xml file in .m2 directory in my system, but I actually entered them from eclipse UI.

Now, when I am clicking finish it's giving me the following error...

I tried with few other repo url after searching google but getting the same error. Where can I get the correct repo url for this archetype??

Thanks in advance...

Answer 1

Add Remote Archetype in your eclipse it will show you that option. Following are the steps:

1. File--->New---> Maven Project---->Next--->Click on tab Configure

2. Separate window will open... Maven-->Archetypes-->Click on Add Remote Catalog--> In Catalog File type " http://repo1.maven.org/maven2/archetype-catalog.xml " and click on Apply and then Ok

3. Now in new Maven Project select Remote Archetype from Catalog and you will find webapp-j2ee14 option there.

I got the same problem and i was creating a simple Web App. I created the MAVEN project first then i deleted it and again when i created it i got this error. So i changed the version of archetype. I was using 2.16 version of the archetype that i was adding to my MAVEN project, changed it to latest 2.26 and it worked for me. You can check the latest version from http://repo1.maven.org/maven2/archetype-catalog.xml

I got this problem as I have deleted a previously created project from Eclipse. Later, I deleted the .metadata file and the project from workspace. Then this problem was resolved.

Answer 4

我遇到了同样的问题，我通过手动删除工作工作区或工作区目录根中未使用的pom.xml文件来解决。

Answer 5

I think the work space has messed up of some reason. These steps below may help

1. Close eclipse
2. delete the .metadata directory
3. Restart the eclipse, pointing to same workspace and try the process to create new maven project

or if this approach didn't work

1. switch to a fresh new workspace and try the same process to create your maven project

This is worked for me!

After working whole day, finally I found the solution. I just went to Eclipse marketlace(help-Eclipse marketplace) and updated maven from there. Now it works wonders. Earlier I was unable to install TestNG plugin from Eclipse marketplace, but now after updating maven from there, Testng plugin successfully installed in my eclipse luna.

I was trying to create a maven archetype quickstart and faced this issue, I have never created any maven project before so for those below is the steps you need to follow -

1. Go to to Run -> Run As -> Maven Install
2. In the project explorer right click on pom.xml file -> Maven -> Update project.

This will for sure resolve the issue.

Eclipse version I am using: 2021-09 (4.21.0)
