Kamil Demecki commented on MECLIPSE-437:
----------------------------------------
This fix introduces error in our build. Eclipse classpath should be compliant
with maven classpath. We have "xml-apis:xml-apis:jar:1.0.b2:provided" on maven
dependencies, and compilation with maven ends with success but there are errors
in eclipse project generated from eclipse plugin in version 2.6. On version
2.5.1 there is no problem - org.eclipse.jdt.launching.JRE_CONTAINER is on first
position.

> Project: Maven 2.x Eclipse Plugin

> While using a newer version of JaxWS (https://jax-ws.dev.java.net/) than the
> one supplied with JDK6 the generated .classpath file in my project directory
> contains all relevant entries headed by the entry for the JRE container.
> ---CODE---
> <classpath>
> <classpathentry kind="src" path="src/main/java"/>
> <classpathentry kind="output" path="target/classes"/>
> <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
> <classpathentry kind="var"
> path="M2_REPO/commons-lang/commons-lang/2.3/commons-lang-2.3.jar"
> sourcepath="M2_REPO/commons-lang/commons-lang/2.3/commons-lang-2.3-sources.jar"/>
> <!-- MORE ENTRIES -->
> <classpathentry kind="var"
> path="M2_REPO/dev/java/net/jaxws-api/2.1.1/jaxws-api-2.1.1.jar"/>
> <!-- EVEN MORE ENTRIES -->
> <classpathentry kind="var"
> path="M2_REPO/commons-logging/commons-logging/1.1/commons-logging-1.1.jar"
> sourcepath="M2_REPO/commons-logging/commons-logging/1.1/commons-logging-1.1-sources.jar"/>
> </classpath>
> ---/CODE---
> As long as the JRE_CONTAINER is mentioned and loaded first my project will
> not compile in Eclipse since I am using operations unique to the newer
> version of JaxWS. When I set the order of the classpath entries in Eclipse
> manually (Properties - Java Build Path - Order and Export, setting the entry
> for JRE_CONTAINER to the 'bottom') my project will compile of course.
> Nicolas de Loof suggested the following in my post to the maven users mailing
> list
> (http://www.nabble.com/Maven2-Eclipse-Plugin---ordering-of-.classpath-entries-p16722527s177.html):
> ---CITE---
> Maybe the eclipse plugin could detect java* and javax* groupIds and force
> them as toplevel ?
> This would require :
> - improve EclipseConfigWriter to have a new getJavaApiDeps(), and remove
> those deps from getDepsOrdered
> - improve EclipseClasspathWriter to write getJavaApiDeps prior to the JRE
> container.
