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

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.

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

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?

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 :(

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.
