Re: [m2e-users] How to open a package in a Maven Project

[Ulrich Schmidt <Ulrich-Dieter.Schmidt@xxxxxxxxxx>]

What I did was just: "New" -> "Maven Project". From the menu displayed the, I selected "Create a simple project" and "Use default workspace location".

Then I specified the following fields:

Group-Id: com.day.cq5.myapp

Artifact: Id: ui

Name: CQ5 MyApp UI

Description: This is the UI module

 

That's it. Now the pom.xml is in error with message:

Multiple annotations found at this line:
    - Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (execution: default-compile,
     phase: compile)
    - Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:testCompile (execution: default-
     testCompile, phase: test-compile)
    - CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:2.3.2 or one of its dependencies could not be
     resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-compiler-plugin:jar:2.3.2: ArtifactResolutionException: Failure to transfer

     maven-compiler-plugin/2.3.2/maven-compiler-plugin-2.3.2.pom

 

And it is not possible to add a java source folder and/or a ja package to the project. I don't see how create a Maven Project with "packaging jar" - there is now selection provided to choose.

I don't know if the tutorial is incorrect, hasn't been followed or is out of date.

 

With a quick scan they are a few things that seems totally wrong for a maven project 

- changing the jdk version in the project properties => this must be specified only in the pom.xml file, eclipse will choose the appropriate jdk automatically

- copying the jars and adding them manually to the project classpath  => Make me wonder why are they using maven at all?

 

That said your problem is probably not related to this. If you still have the error, I'd suggest to retry with a new project with packaing jar.

Send all the errors message if you still have some.

 

 

JDT will only allow you to create a Java package in a folder that has been designated as a Java Source folder; as I mentioned in my previous message this probably means you declared the wrong packaging type in the maven pom.

As I already said, I'm working on a sample: "CQ5: Developing with Eclipse"
( http://dev.day.com/docs/en/cq/current/developing/developmenttools/developing_with_eclipse.html?cq_ck=1360336344421#Creating%20the%20Project%20Structure%20in%20Eclipse).
This sample requires plugin "Maven Integration for Eclipse" to be installed.
After creating a Maven Project I'm supposed to create a package within the
folder src/main/java - that's all.
The sample isn'T a new one - so I'm convinced that it should normally work. I
want to make sure that I did not miss something to install or activate which has
been forgotten in this sample.
Any idea what I can do here?
