如何设置maven 3本地插件库

Question

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<pluginRepositories>搜索插件.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,<url>但它不起作用.

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 应该有所帮助
