Arnaud Heritier updated MAVEN-1576:
-----------------------------------
Fix Version: (was: 1.1-beta-3)
> expecects ForeheadClassLoader, finds sun.misc.Launcher$AppClassLoader
> ---------------------------------------------------------------------
>
> Key: MAVEN-1576
> URL: http://jira.codehaus.org/browse/MAVEN-1576
> Project: Maven
> Type: Bug
> Components: core
> Versions: 1.0.2
> Environment: Linux
> Reporter: Willie Milnor
>
>
> I am trying to get around using com.werken.forehead.Forehead to run Maven,
> and instead use my own class that extends org.apache.maven.cli.App. However,
> I get the following error no matter what I try:
> java.lang.ClassCastException: sun.misc.Launcher$AppClassLoader
> at
> org.apache.maven.plugin.PluginManager.processDependencies(PluginManager.java:437)
> at
> org.apache.maven.plugin.PluginManager.attainGoals(PluginManager.java:642)
> at org.apache.maven.MavenSession.attainGoals(MavenSession.java:263)
> at MyApp.myDoMain(MyApp.java:80)
> at MyApp.main(MyApp.java:575)
> I know that this is caused by the following line:
> ForeheadClassLoader projectClassLoader =
> (ForeheadClassLoader)project.getContext().getClassLoader();
> I assume that when com.werken.forehead.Forehead is called, it somehow sets
> the class loader (for the context) to an instance of ForeheadClassLoader; but
> by calling my class directly, the context uses an instance of
> sun.misc.Launcher$AppClassLoader.
> I am able to run my own class calling com.werken.forehead.Forehead first (I
> edited the forehead.conf file), and it works as it should. I tried setting
> the class loader for the context using a ForeheadClassLoader, but that loader
> is changed somewhere along the way to processing the dependencies.
> Is there a way around this problem? I am using maven 1.0.2...is there a
> newer beta version of maven that expects simply a ClassLoader rather than a
> ForeheadClassLoader?
