Question

Currently I have perforce that I am importing my project into eclipse from. After I import my project into eclipse I right click on the project go to configure and convert to maven project. After doing all of this I do NOT have autocomplete for the code working and I do NOT have ctrl+click working.

System Specs:

• OS: Windows 7 x64
• RAM: 8gb
• CPU: Intel core i5
• HDD: 128gb SDD
• Eclipse Version: Juno 4.2 JavaEE
• Maven m2e Version: 1.1.0
• Perforce Version: 2012.2.486944

Attempts at a Fix

1. I have noticed that when I right click on my project and look to go to Java Build Path it does not exist.
2. Under my right click menu properties and under builders I only have "Maven Project Builder"
3. I have tried to add the proper <buildCommand> for the java builder and the proper <natures> in the .project file. This does NOT fix my issue but does add the Java Build Path I couldn’t see in 1. (below is my unaltered .project file)
4. I have navigated to the .metadata>.plugins and deleted the org.eclipse.jdt.core to eclipse rebuild its indices.

Error Received when trying ctrl+click autocomplete or a right click>References>Workspace

The resource is not on the build path of a Java project

.project file

    <?xml version="1.0" encoding="UTF-8"?>
    <projectDescription>
        <name>project</name>
        <comment></comment>
        <projects>
        </projects>
        <buildSpec>
            <buildCommand>
                <name>org.eclipse.m2e.core.maven2Builder</name>
                    <arguments>
                    </arguments>
            </buildCommand>
        </buildSpec>
        <natures>
            <nature>org.eclipse.m2e.core.maven2Nature</nature>
        </natures>
    </projectDescription>

Is there something simple that I have overlooked, or a step that I forgot to do? Any help regarding this issue would be great.

(*I have searched though issues relating to the ctrl+click and the autocomplete but none of the solutions that I have found have helped and none seem to match the eclipse+perforce+maven issue, but sorry in advance if this topic was covered in a different post)

Answer 1

Alright here is what I did and found out.

I started over with a new copy of eclipse 4.2 EE and redownloaded all of the plugins that I needed: m2e and perforce

If you have a flat Maven Project

1. Import the project from perforce, right click on the project>configure>Convert to Maven Project
2. Converting the flat project to a Maven Project indexed everything allowing for the ctrl+click/ctrl+space functionality

If you have a multi module Maven Project

1. Check out the project using the perforce plugin into your workspace
2. Import said project as an Existing Maven Project
3. Eclipse/Maven will automatically find all of the poms underneath the parent directory and build/index your workspace
4. After that same as above the ctrl+click/ctrl+space functionality should work

My oversight was that the project I was having issues with I did not realize was a multi module maven project and importing it from perforce and trying to convert the parent folder to a maven project did not cause maven to look at all of the poms in the parent’s sub-directories. Hope this helps anyone else having this issue.
