Question

我正在尝试使用m2eclipse api按原型导入项目。我的代码在这里：

    RemoteCatalogFactory remoteCatalogFactory = new RemoteCatalogFactory("http:/server1/archetype-catalog.xml", null, true);
    ArchetypeCatalog catalog = remoteCatalogFactory.getArchetypeCatalog();
    List<Archetype> archetypes = catalog.getArchetypes();
    for (Archetype archetype : archetypes){
        System.out.println(archetype.getArtifactId());
    }

m2eclipse版本是：0.12.1。得到以下例外：

1) Error injecting: org.sonatype.maven.wagon.AhcWagon
  at ClassRealm[plexus.core, parent: null]
  while locating org.apache.maven.wagon.Wagon annotated with @com.google.inject.name.Named(value=http)

在调试期间，我发现bundleloader正在使用org.maven.ide.eclipse的bundle classloader来加载AhcWagon类。因为maven embedder bundle没有导出AhcWagon的包，所以无法加载它。

但我的问题是：调用者（plexus-classworlds.jar）在maven嵌入器包中，而AhcWagon（在wagon-ahc.jar中）是在同一个包中。为什么不使用maven embedder的bundle loader来加载AhcWagon？

使用此API有什么问题吗？

太棒了！如果有任何示例代码。

Answer 1

m2eclipse0.12.1的错误，需要在清单中导出org.sonatype.maven.wagon。

获取原型目录失败（无法加载Ahcwagon）-m2e-0.12.1
