无法计算构建计划错误

Question

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

我已尝试过所有搜索结果但未找到解决方案。多次删除存储库，仍然得到相同的错误。此外，我找不到我的settings.xml文件，我也无法创建自己的文件。如果有人可以向我提供settings.xml文件并建议所需的更改。
