M2e

M2eclipse is a Plug-in for the Eclipse IDE that defines Eclipse Project structures by analyzing Maven Project models.

Maven

Apache Maven is a build automation and project management tool used primarily for Java projects



Elete directory update

Example

"If your project is already imported update the project configuration right-click on the project then maven v update project configuration;the m2e plugin doesn t use eclipse defaults the m2e plugin derives the settings from the pom.xml"

from question  

What causes imported Maven project in Eclipse to use Java 1.5 instead of Java 1.6 by default and how can I ensure it doesn't?

"Elete that directory and then do maven - update project this should fix your problem;by the way mvn eclipse eclipse is almost never the right thing to do it s much better to use m2e for your eclipse integrations as m2e works much more seamlessly"

from question  

How do I build my Maven pom in Eclipse?

Platform integration additional

Example

"Maven 2 has a steeper learning curve but provides a much richer set of functionality for building your projects and eclipse integration through m2e or iam"

from question  

What is the most elegant solution to managing various Java external libraries?

"M2e is also a platform that let others provide better integration with additional maven plugins android web development etc."

from question  

How can I add dependency to Eclipse

Others

Example

I don t understand where many ide using in back end build tools why spring source or other framework forcing us to use maven again i thinks instead of using maven it is better to build plugins to sts for configure and download jars automatically for bootstrapping project;the maven structure and m2e really annoy me .it is just dependency inside another dependency

from question  

* (no title is found for this review)

An internal error occurred during importing maven projects .unsupported iclasspathentry kind 4;where is the value kind var that m2e does not recognize and therefore throws the error

from question  

How to fix error "Updating Maven Project". Unsupported IClasspathEntry kind=4?

Moreover i m using m2e the maven plugin for eclipse so it seems that the compatibility of any maven plugins that might work by themselves is even less likely with m2e

from question  

Use Maven to compile a Fortran subroutine (per-platform) and link to JNA

I recommend using m2e when working with maven in eclipse

from question  

What does "The word " is not correctly spelled mean"?

You have to import your project as a maven project not as a normal java project to eclipse;then m2e gets active and will download the libraries

from question  

How can I configure and use auto-complete and other Eclipse features within a Maven-managed project?

The way eclipse handles maven projects is currently through the m2e plugin;m2e does not invoking maven underneath but parses the pom.xml files and for each plugin mentioned invoke code explicitly written to behave identically inside m2e as the plugin

from question  

Error importing Maven project in eclipse

In other words m2e is more friendly to the maven way

from question  

Maven2 Eclipse integration

In my first round with maven i thought i was smarter than maven s standards and used my own - which was actually a hybrid with the eclipse defaults

from question  

What's the "correct" way to build an eclipse project for a web app using maven?

The jdk compliance level is derived from the maven project not the other way around;in other words you need to configure the maven compiler plugin for 1.6 level compliance and then m2e will derive the appropriate settings under eclipse

from question  

M2eclipse sets JDK compliance to 1.4

With 0.13 m2e this no longer works as the maven builder appears to put things in target your-artificat-version-snapshot web-inf classes

from question  

Eclipse - JUnit / m2eclipse classpath problem

If you re doing osgi maven is less great;m2e however is less helpful and in my experience only leads to confusing headaches

from question  

Is Maven a good solution for my Application

Maven isn t looking in the wrong repository and dependencies on hibernate 3.5.1 artifacts are available in the jboss repository and get resolved;however m2e is very likely not configured to use the nexus index of the jboss repository and you need to enable this index in your m2e installation

from question  

Why does Maven is looking in the wrong repo?

Alternately you can provide a goal in the maven build configuration;now as for the warning copy-dependencies is not supported by m2e it means that m2e does not support this plugin

from question  

M2e: copy-dependencies is not supported by m2e
