jboss plexus中的maven索引搜索错误
您好,我试图从部署在 jboss 上的 Seassion bean 中搜索 Maven 存储库,
此代码适用于 javaSE
PlexusContainer plexus = new DefaultPlexusContainer(); NexusIndexer n = (NexusIndexer) plexus.lookup(NexusIndexer.class); IndexUpdater iu = (IndexUpdater) plexus.lookup(IndexUpdater.class); // DefaultNexusIndexer n = new DefaultNexusIndexer(); List indexCreators=new ArrayList(); // IndexingContext c = n.addIndexingContext("test", "test",new File( "/home/tomas/Desktop/test"),new File( "/home/tomas/Desktop/index"), "http://repository.jboss.org/", null); Directory tempIndexDirectory = new RAMDirectory(); // IndexCreator min = new MinimalArtifactInfoIndexCreator(); // MavenPluginArtifactInfoIndexCreator mavenPlugin = new MavenPluginArtifactInfoIndexCreator(); // MavenArchetypeArtifactInfoIndexCreator mavenArchetype = new MavenArchetypeArtifactInfoIndexCreator(); // JarFileContentsIndexCreator jar = new JarFileContentsIndexCreator(); // IndexCreator min = plexus.lookup( IndexCreator.class, MinimalArtifactInfoIndexCreator.ID ); IndexCreator mavenPlugin = plexus.lookup( IndexCreator.class, MavenPluginArtifactInfoIndexCreator.ID ); IndexCreator mavenArchetype = plexus.lookup( IndexCreator.class, MavenArchetypeArtifactInfoIndexCreator.ID ); IndexCreator jar = plexus.lookup( IndexCreator.class, JarFileContentsIndexCreator.ID ); indexCreators.add(min); indexCreators.add(mavenPlugin); indexCreators.add(mavenArchetype); indexCreators.add(jar); IndexingContext c = n.addIndexingContext( "temp", "test", new File("/home/tomas/Desktop/mavenTest"), tempIndexDirectory, "http://repository.jboss.org/maven2/", null, indexCreators ); IndexUpdateRequest ur=new IndexUpdateRequest(c); ur.setForceFullUpdate(true); iu.fetchAndUpdateIndex(ur); // for (String s : c.getAllGroups()) { // System.out.println(s); // } BooleanQuery q = new BooleanQuery(); q.add(n.constructQuery(ArtifactInfo.GROUP_ID, "*"), Occur.SHOULD); FlatSearchRequest request = new FlatSearchRequest(q); FlatSearchResponse response = n.searchFlat(request); for (ArtifactInfo a : response.getResults()) { String bUrl=url+a.groupId+"/"+a.artifactId+"/"+a.version+"/"; String fileName=a.artifactId+"-"+a.version; System.out.println(bUrl+fileName+"."+a.packaging); }
在 jboss 上出现此异常:
org.codehaus.plexus.component.repository.exception.ComponentLookupException: java.util.NoSuchElementException role: org.sonatype.nexus.index.NexusIndex
据我所知,这与构建路径无关,因为我可以实例化 DefaultNexusIndexer (它确实不起作用,因为丛必须注射) 可能是神经丛的问题,
请帮忙
Hi Im trying to search a maven repository from a seassion bean deployed on jboss
this code works on javaSE
PlexusContainer plexus = new DefaultPlexusContainer(); NexusIndexer n = (NexusIndexer) plexus.lookup(NexusIndexer.class); IndexUpdater iu = (IndexUpdater) plexus.lookup(IndexUpdater.class); // DefaultNexusIndexer n = new DefaultNexusIndexer(); List indexCreators=new ArrayList(); // IndexingContext c = n.addIndexingContext("test", "test",new File( "/home/tomas/Desktop/test"),new File( "/home/tomas/Desktop/index"), "http://repository.jboss.org/", null); Directory tempIndexDirectory = new RAMDirectory(); // IndexCreator min = new MinimalArtifactInfoIndexCreator(); // MavenPluginArtifactInfoIndexCreator mavenPlugin = new MavenPluginArtifactInfoIndexCreator(); // MavenArchetypeArtifactInfoIndexCreator mavenArchetype = new MavenArchetypeArtifactInfoIndexCreator(); // JarFileContentsIndexCreator jar = new JarFileContentsIndexCreator(); // IndexCreator min = plexus.lookup( IndexCreator.class, MinimalArtifactInfoIndexCreator.ID ); IndexCreator mavenPlugin = plexus.lookup( IndexCreator.class, MavenPluginArtifactInfoIndexCreator.ID ); IndexCreator mavenArchetype = plexus.lookup( IndexCreator.class, MavenArchetypeArtifactInfoIndexCreator.ID ); IndexCreator jar = plexus.lookup( IndexCreator.class, JarFileContentsIndexCreator.ID ); indexCreators.add(min); indexCreators.add(mavenPlugin); indexCreators.add(mavenArchetype); indexCreators.add(jar); IndexingContext c = n.addIndexingContext( "temp", "test", new File("/home/tomas/Desktop/mavenTest"), tempIndexDirectory, "http://repository.jboss.org/maven2/", null, indexCreators ); IndexUpdateRequest ur=new IndexUpdateRequest(c); ur.setForceFullUpdate(true); iu.fetchAndUpdateIndex(ur); // for (String s : c.getAllGroups()) { // System.out.println(s); // } BooleanQuery q = new BooleanQuery(); q.add(n.constructQuery(ArtifactInfo.GROUP_ID, "*"), Occur.SHOULD); FlatSearchRequest request = new FlatSearchRequest(q); FlatSearchResponse response = n.searchFlat(request); for (ArtifactInfo a : response.getResults()) { String bUrl=url+a.groupId+"/"+a.artifactId+"/"+a.version+"/"; String fileName=a.artifactId+"-"+a.version; System.out.println(bUrl+fileName+"."+a.packaging); }
On jboss a get this exception :
org.codehaus.plexus.component.repository.exception.ComponentLookupException: java.util.NoSuchElementException role: org.sonatype.nexus.index.NexusIndex
As far as I know this has nothing to do with the build path because i can instantiate the DefaultNexusIndexer (which does not work because plexus hast to make his injections)
It is probably something with plexus

顺便说一句,它是最新版本
this one works

btw its the newest version
您是否检查过您的设备上是否有相同的 Plexus 配置文件类路径?
我想在您的 SE 测试中,您的类路径上确实有一个 plexus 配置文件,其中包含角色 org.sonatype.nexus.index.NexusIndex 的组件描述符,而您的 JBoss 上可能缺少该描述符。
Have you checked that you have the same Plexus configuration files on your classpath?
I suppose that in your SE test you do have a plexus configuration file on the classpath which contains a component descriptor for role
org.sonatype.nexus.index.NexusIndex
which might be missing on your JBoss.
