This issue is depended upon by:

~~MAVEN-1756~~ Backward Incompability : Usage of xml entities in maven.xml doesn't work in maven 1.1 beta 1 & 2

Description

« Hide

Because maven 1.1 works only with a jdk >= 1.4 whereas maven 1.0 requires at least the jdk 1.3, we removed xerces from the distribution (the xml parser API implemented by crimson is available in the jdk)
The problem is that there's some bugs in crimson that are really annoying. Particularly there are a lot of issues with entities management.
To fix them we have to readd xerces in the distribution.

We'll upgrade to xerces 2.6.2

The bootstrap (with tests for all plugins) was tested with the jdk 1.4.2 and the jdk 1.5
For the jdk 1.5 I needed to change the permSize : -XX:MaxPermSize=128m

xmlParserAPIs is deprecated.
From: Michael Glavassevich :
===
xmlParserAPIs.jar hasn't existed since Xerces-J 2.6.2. The jar which is
now distributed with Xerces is called xml-apis.jar and originates from the
xml-commons [1] project. Xerces-J 2.8.0 bundled xml-commons external
1.3.03 [2] which can be found here [3] on ibiblio.
[1] http://xml.apache.org/commons/
[2] http://svn.apache.org/viewcvs.cgi/xml/commons/tags/xml-commons-external-1_3_03/java/external/
[3] http://www.ibiblio.org/maven2/xml-apis/xml-apis/1.3.03/
===
Xerces-J 2.8.0 also depends on the xml-commons resolver 1.1 [1]. It has
been a dependency since Xerces-J 2.6.1.

I upgraded the core and the plugins to use :

Xerces 2.8.0.
xml-apis 1.3.03.
xml-resolver 1.1.
It's tested with maven 1.1 beta 3 + jdk 1.4.2 & 1.5
More tests are needed with maven 1.0.2 + jdk 1.3 & 1.4 & 1.5

Thanks Arnaud for making this change and publishing the snapshots.

I am running your 4/30/06 M1.1-beta-3 snapshot, and it fixes a "SAXParser class not found" problem I had with trying to get QALab maven plugin to run. I also had to adjust a few of its dependencies (it was proven only on M1.0.2 according to Benoit, its author), but after that, nothing I did could get rid of that exception.

Our CI product builds and nightly site gen are pounding on your snapshots daily...

(Per Arnaud's email request: Can you tell us what you had to change to use this plugin with maven 1.1)
The dependecies changed to make it work were all parser related:

Removed dependency on xercesImpl jar
Added dependency on xerces 2.4.0 jar
Upgraded Xalan dependency to 2.7.0 jar

Then the last problem was:
java.lang.ClassNotFoundException: org/apache/xerces/parsers/SAXParser

Upgrading to m1-b3-snapshot of 4/30/06 solved that one. I'm pretty sure I was using the snapshot just before 4/30/06 that did not work.
