> Key: MNG-5122
> URL: https://jira.codehaus.org/browse/MNG-5122
> Project: Maven 2 & 3
> Issue Type: Bug
> Components: Class Loading, Embedding
> Affects Versions: 3.0.3
> 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.
> [ERROR] com.google.inject.internal.util.ComputationException:
