如何设置maven 3本地插件库

由于一些限制，我需要一个完全脱机的maven存储库。 根据http://cwiki.apache.org/confluence/display/MAVEN/PluginResolutionException ，仅搜索以查找插件。 所以我想知道如何配置maven来查找本地文件系统中的插件。 我在设置时尝试使用“file：//”前缀，但它不起作用。

 DEBUG] Verifying availability of /home/dsun/.m2/repository/org/apache/karaf/tooling/features-maven-plugin/2.3.0/features-maven-plugin-2.3.0.jar from [central (http://repo1.maven.org/maven2, releases=true, snapshots=false, managed=false)] [ERROR] Plugin org.apache.karaf.tooling:features-maven-plugin:2.3.0 or one of its dependencies could not be resolved: The repository system is offline but the artifact org.apache.karaf.tooling:features-maven-plugin:jar:2.3.0 is not available in the local repository. -> [Help 1] org.apache.maven.plugin.PluginResolutionException: Plugin org.apache.karaf.tooling:features-maven-plugin:2.3.0 or one of its dependencies could not be resolved: The repository system is offline but the artifact org.apache.karaf.tooling:features-maven-plugin:jar:2.3.0 is not available in the local repository. dsun@localhost:> ls /home/dsun/.m2/repository/org/apache/karaf/tooling/features-maven-plugin/2.3.0/features-maven-plugin-2.3.0.jar /home/dsun/.m2/repository/org/apache/karaf/tooling/features-maven-plugin/2.3.0/features-maven-plugin-2.3.0.jar

Answer 1

最后，我发现了问题，插件目录中有一个名为_maven.repositories的文件，删除文件后，一切正常！

从Maven 3.1-alpha-1开始，命令行选项-llr/--legacy-local-repository或系统属性-Dmaven.legacyLocalRepo=true应该有帮助
