将xom添加到Maven项目时出现问题

Question

我正在尝试在Maven项目中使用xom，但我收到错误 Description Resource Path Location Type ArtifactDescriptorException: Failed to read artifact descriptor for xom:xom:jar:1.2.5: ArtifactResolutionException: Failure to transfer xom:xom:pom:1.2.5 from http://repo2.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of repo2_maven_org has elapsed or updates are forced. Original error: Could not transfer artifact xom:xom:pom:1.2.5 from/to repo2_maven_org (http://repo2.maven.org/maven2): null to http://repo2.maven.org/maven2/xom/xom/1.2.5/xom-1.2.5.pom pom.xml /tahrir line 1 Maven Dependency Problem

我的pom.xml看起来像

Answer 1

通过清除.m2/rerepository文件夹并从头开始重新构建项目来管理以解决问题。
