eclipse - 插件 org.apache.maven.plugins :maven-resources-plugin:2. 5 或其依赖项之一无法解析:UnresolvedAddressException

Question

我已经将 Maven 与 Eclipse 集成并尝试创建一个 Maven 项目。每次我尝试创建项目时，它的 POM.xml 都会显示错误。

Multiple annotations found at this line: - Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (execution: default-compile, phase: compile) - Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:testCompile (execution: default-testCompile, phase: test-compile) - CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:2.3.2 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-compiler-plugin:jar:2.3.2: ArtifactResolutionException: Failure to transfer org.apache.maven.plugins:maven-compiler-plugin:pom:2.3.2 from htt:///repo.maven.apache.org/maven2 was cached in the local
repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-compiler-plugin:pom:2.3.2 from/to central (htt:///repo.maven.apache.org/maven2): null to htt://
repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-compiler-plugin/2.3.2/maven-compiler-plugin-2.3.2.pom

如果我尝试运行 maven-install 或任何 maven 运行选项。我得到这个错误

我该怎么办？

Answer 1

您实际上不必从 .m2\repository 目录中删除所有内容。只是“有问题的库”的目录，在您的示例中 YOUR_MAVEN_REPO.m2\repository\org\apache\maven\plugins\maven-compiler-plugin 并删除 2.3.2 文件夹。

然后右键单击Eclipse和Maven中的项目->更新项目。你可能会得到一个不同的错误，你必须重复这个过程。做3-4次应该没问题...
