My Attempt at Bulding Mule 1.4.x

I thought I'd take a crack at building the Mule source, which uses Maven for its builds:

$ svn export http://svn.codehaus.org/mule/branches/mule-1.4.x
$ cd mule-1.4.x
$ mvn validate

I was first presented with the following error:

Missing:
----------
1) org.apache.maven.wagon:wagon-webdav:jar:RELEASE

Added the Mule repositories:

<repository>
  <id>muleforge</id>
  <url>http://repository.muleforge.org</url>
  <name>MuleForge Repository</name>
</repository>
<repository>
  <id>mule.dependencies</id>
  <url>http://dist.codehaus.org/mule/dependencies/maven2/</url>
  <name>Mule Dependencies Repository</name>
</repository>
<!-- For the Abdera dependencies -->
<repository>
  <id>apache-incubating</id>
  <name>Apache Incubating Repository</name>
  <url>http://people.apache.org/repo/m2-incubating-repository/</url>
</repository>

Now the version issue for wagon-webdav was resolved. From the mvn validate output:

    WAGON_VERSION: 1.0-beta-2

My next problem was that I did an export and not a checkout:

[INFO] Updating project files from SCM: skipped.
Provider message:
The svn command failed.
Command output:
svn: '.' is not a working copy

[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Cannot get the revision information from the scm repository : 
Error!

So I replaced my export with a checkout:

$ svn co http://svn.codehaus.org/mule/branches/mule-1.4.x .

Now a Java version problem:

[WARNING] Rule 1: org.apache.maven.plugin.enforcer.RequireJavaVersion failed with message: Detected JDK Version: 1.6.0
 is not in the allowed range [1.4.2,1.5.0).

As I only have Java 6 on my machine:

$ java -version
java version "1.6.0"
OpenJDK Runtime Environment (build 1.6.0-b09)
OpenJDK Server VM (build 1.6.0-b09, mixed mode)

I changed the configuration of the enforcer plugin to allow up to Java 1.6.0:

<requireJavaVersion>
  <!-- minimum version is 1.4.2, Java 5 and higher not allowed -->
  <!-- <version>[1.4.2,1.5.0)</version> -->
  <version>[1.4.2,1.6.0]</version>
</requireJavaVersion>

The Build Guide lists I could of skipped the enforcer with:

$ mvn -DskipEnforcer=true

After running:

$ mvn test

I got a lot farther, but the amount of test errors are kind of scary:

Tests run: 131, Failures: 10, Errors: 46, Skipped: 0

A common error was a found in the output files in tests/functional/target/surefire-reports was:

org.mule.test.config.MuleClasspathConfigBuilderTestCase.txt:org.mule.config.ConfigurationException:
Failed to parse configuration resource
"file:/home/prystasj/workspace/mule-1.4.x/tests/functional/target/test-classes/test-xml-mule-config.xml"

I was able to read the file with Groovy's XmlSlurper just fine:

#!/usr/bin/env groovy
file = new File(args[0])
def xml = new groovy.util.XmlSlurper().parse(file)
println xml

I tried the build with skipping the tests:

$ mvn -DskipTests package

But I got a compilation error. Maybe someday I'll take the time to figure out whats going wrong. I was still able to generate some Eclipse project files though:

$ mvn eclipse:eclipse

So I can still take a good look at the source, which is good enough.
