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?
