I’m just trying Maven4MyEclipse for the first time. I’ve just set up a straightforward test project (called testMavenProject) based on the tutorial:

“Creating a Maven Project using Maven4MyEclipse”.

The pom is created with a red cross and the following 5 errors are listed under problems – please can you advise? (I’ve also appended pom.xml):

Missing artifact javax.activation:activation:jar:1.0.2:provided
Missing artifact javax.mail:mail:jar:1.3.1:provided
Missing artifact javax.xml:namespace:jar:1.1.0:provided
Project ‘testMavenProject’ is missing required library: “C:\Users\zoe james\.m2\repository\javax\activation\activation

Here is the pom.xml:

Can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

Also, can you switch to new workspace, create a new maven project and check if you are able to reproduce this issue.

Let me know what result you get.

[cusdx]

Thanks for your reply. I’ve pasted the Installation Details below. I also tried recreating the problem in a new workspace as you suggested, and did reproduce the error.

It’s a confusing workflow. MyEclipse should’ve initialized your repository when you created your web project but due to some Maven problem it didn’t. Can your workstation access Internet and/or some Maven repository in your network? Note: MyEclipse uses core Maven tasks and if they were not downloaded Maven will not work.

To make MyEclipse do another attempt at initializing the repository:
1. Restart MyEclipse.
2. Create dummy web project with Maven support. You may delete it right after you created it.
3. Right-click your original web project and select Maven4MyEclipse -> Update Dependencies

[cusdx]

Yes, my workstation definitely has internet access. I can even access the internet from within myEclipse.

As soon as I set up the dummy web maven project, I get the following error message – I noticed it in the online demo so assume it doesn’t matter:

“Some Maven goals may require a JDIK to execute properly; Please make sure that MavenJDK preference is pointing to a JDK…”

Behind that are flashing a lot of “BUILD FAILED” messages. I just managed to copy the end of one below, hope this gives a clue:

It looks like you have corrupted Maven local repository. Can you rename ~/.m2 folder so the Maven tries to recreate it?

Note: Maven goals like compile will not execute unless you select proper JDK on the Maven preference page. MyEclipse build will still work though.

I tried – import goal works on JRE so this is not a cause of the problem you see. Did you use some other Maven version on your workstation?

[cusdx]

Eugene,

Thanks for your work on this. This is looking better. Through recreating the maven repository I have discovered that I had a J2EE specification level/ compiler compliance clash – I’d selected J2EE spec of EE 5.0 but hadn’t changed the compiler compliance. Now a lot more good things are happening.

The complaint about the JDK for maven appears to be because although I had selected a JDK for maven (jdk1.6.0_12), I needed to change the default selected JRE to match – I did this and that warning has gone.

I am still getting some “missing artifact” messages though, both in the initial build and when I do “update dependencies”. They are in red:

04/03/09 14:03:14 GMT: Missing artifact javax.activation:activation:jar:1.0.2:provided
04/03/09 14:03:14 GMT: Missing artifact javax.mail:mail:jar:1.3.1:provided
04/03/09 14:03:14 GMT: Missing artifact javax.xml:namespace:jar:1.0.1:provided

Although it says “provided”, if I update dependencies again they come up again.

Is this an issue?

Zoe

Did you try to create web project after you redid Maven local repository? Note: you need to restart MyEclipse before doing this 🙁

[cusdx]

Looks like I might be in business now. I tried again and got some bits in red (below), but when I updated the dependencies on the existing project – no red! Many thanks for your help.
