MavenCli com.google.inject.internal.util.ComputationException:
java.lang.NoClassDefFoundError:

------------------------------------------------------------------------------------------------------------------------------------------------
Key: MNG-5122
URL: https://jira.codehaus.org/browse/MNG-5122
Project: Maven 2 & 3
Issue Type: Bug
Components: Class Loading, Embedding
Affects Versions: 2.2.1
Environment: Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200)
Java version: 1.6.0_16
Java home: C:\Programme\Java\jdk1.6.0_16\jre
Default locale: de_DE, platform encoding: Cp1252
OS name: "windows 7" version: "6.1" arch: "x86" Family: "windows"
Reporter: Kati Golbang
Attachments: build.log, components.xml, pom.xml
I want to use MavenCli in order to use Maven programatically within an
installer (IzPack).
pom.xml (see attachment).
I'm using
<dependency>
<groupId>org.apache.maven</groupId>
<artifactId>maven-embedder</artifactId>
<version>3.0-beta-3</version>
</dependency>
Note that all dependencies are unzipped and part of the final installer jar
(target/product-installer.jar). The components.xml contains all available
components.xml files (merged by plexus-component-metadata plugin).
how to build: mvn -X clean install > build.log
At runtime (java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,address="8000"
-jar target/wigeoweb-installer.jar) following code is executed:
MavenCli cli = new MavenCli();
int result = cli.doMain(new String[]{"compile -X"},
"C:/Develop/Experiments/webservercontext-maven-plugin", //Own plugin
System.out, System.out);
System.out.println("result: " + result);
It terminates with exception while initializing plexus container (there's the
place where the debugger exits):
Exception:
Listening for transport dt_socket at address: 8000
[ERROR] Error executing Maven.

Source Code:
private void container( CliRequest cliRequest )
throws Exception
{

{ cliRequest.classWorld = new ClassWorld( "plexus.core",
Thread.currentThread().getContextClassLoader() ); }
DefaultPlexusContainer container = this.container;
if ( container == null )
{
ContainerConfiguration cc = new DefaultContainerConfiguration()
.setClassWorld( cliRequest.classWorld )
.setName( "maven" );
*container = new DefaultPlexusContainer( cc ); //<<<<<<<<<<<<<<<<<<<<<<
EXCEPTION THROWN*
container.setLoggerManager( new MavenLoggerManager( logger ) );
container.getLoggerManager().setThresholds(
cliRequest.request.getLoggingLevel() );
customizeContainer( container );
if ( cliRequest.classWorld == classWorld )
{ this.container = container; }
}
maven = container.lookup( Maven.class );
executionRequestPopulator = container.lookup(
MavenExecutionRequestPopulator.class );
modelProcessor = createModelProcessor( container );
settingsBuilder = container.lookup( SettingsBuilder.class );
dispatcher = (DefaultSecDispatcher) container.lookup( SecDispatcher.class,
"maven" );
}
thank you
