Hi folks, sorry for the spam. I'm also posted on users. Whats the correct list for such plugin developer questions?
--- I've tried the whole day on how can i embedd a call for a maven goal into my java src. I'm working with maven-3.0-beta-1. Here are my sample snippets which the appropriate error messages: public class MavenEmbedTest { public static void main(String[] args) { File workingDir = new File("/path/to/a/maven/project"); // [1] MavenCli cli = new MavenCli(); cli.doMain(new String[] { "package" }, workingDir.getAbsolutePath(), System.out, System.err); // [2] DefaultMaven maven = new DefaultMaven(); DefaultMavenExecutionRequest request = new DefaultMavenExecutionRequest(); request.setBaseDirectory(workingDir); List<String> goals = new ArrayList<String>(); goals.add("package"); request.setGoals(goals); MavenExecutionResult result = maven.execute(request); // [3] File pom = new File(workingDir, "pom.xml"); DefaultProjectBuilder projectBuilder = new DefaultProjectBuilder(); ProjectBuildingResult project = projectBuilder.build(pom, new DefaultProjectBuildingRequest()); } } As result of [1] running as local java program, i got: [ERROR] Error executing Maven. [ERROR] Cycle detected in component graph in the system: [ERROR] Caused by: Cyclic requirement detected [ERROR] Caused by: Edge between 'Vertex{label='org.apache.maven.lifecycle.LifecycleExecutor:default'}' and 'Vertex{label='org.apache.maven.project.MavenProjectBuilder:default'}' introduces to cycle in the graph org.apache.maven.project.MavenProjectBuilder:default --> org.apache.maven.project.ProjectBuilder:default --> org.apache.maven.model.building.ModelBuilder:default --> org.apache.maven.model.plugin.LifecycleBindingsInjector:default --> org.apache.maven.lifecycle.LifecycleExecutor:default --> org.apache.maven.project.MavenProjectBuilder:default As result of [2] I got a NullPointerException, because of the annotated components were not injected. How can I start the PlexusContainer correctly? The result of [3] is "RepositorySystem is missing" which is nearly the same problem as in [2]. What I need is to start a maven plugin, which is deployed in my local repo and is based on maven3. Could anybody help my please? Are there any samples or code snippets, which I could use? Currently I'm working on a hudson build trigger for maven3 based free style projects. The trigger checks updates on the maven dependencies and the schedules a rebuild.
