IdeUtils determine unresolved values from maven-compiler-plugin
---------------------------------------------------------------
Key: MECLIPSE-463
URL: http://jira.codehaus.org/browse/MECLIPSE-463
Project: Maven 2.x Eclipse Plugin
Issue Type: Bug
Reporter: Oliver Pehnke
Background:
-----------------
In our project we use a profiles.xml where the properties of the project are
configured. The profiles.xml contains also the following properties:
{code}
...
<project.javac.source>1.5</project.javac.source>
<project.javac.target>1.5</project.javac.target>
...
{code}
The maven-compiler-plugin is configured with these settings, like:
{code}
...
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<compilerVersion>${project.javac.compiler}</compilerVersion>
<source>${project.javac.source}</source>
<target>${project.javac.target}</target>
...
{code}
Problem:
------------
If you run the command:
{code}
mvn eclipse:eclipse
{code}
The plugin will create for each module a .project .classpath and a .settings
folder containing a "org.eclipse.jdt.core.prefs" file. The content created
looks like this:
{code}
#Fri Jun 20 16:48:19 CEST 2008
org.eclipse.jdt.core.compiler.codegen.targetPlatform=${project.javac.target}
eclipse.preferences.version=1
org.eclipse.jdt.core.compiler.source=${project.javac.source}
org.eclipse.jdt.core.compiler.compliance=${project.javac.source}
{code}
Of course Eclipse is unable to determine the version and will complain about an
unknown version of the java source and target.
Root of problem:
-----------------------
For me it seems the process of determining the target and source values in the
class "IdeUtils" is the problem. The variables need to be resolved before using
it. This is an issue of the used method "findCompilerPluginSettingInPlugins" or
the maven API itself.
