签出java maven项目后，我的pom一直都有一些错误。 maven clean和maven install就像一个魅力，但每次出现以下错误时，maven更新项目或下载源代码/ java doc都会给我：
Could not download sources or javadoc
Could not read maven project
Some problems were encountered while processing the POMs:
[ERROR] Non-resolvable import POM: Failure to transfer io.github.jhipster:jhipster-dependencies:pom:3.0.1 from https://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.

我在公司代理中，我已经在Eclipse中对其进行了配置。
我过去与Maven无关，每次都只对我有用。该项目是使用jHipster设置的。
希望有人可以帮助我。
提前感谢。
对于每个想知道我如何解决此问题的人：
首先像已经提到的khmarbaise，这是一个代理问题。它已经在eclipse中进行了配置，因此我假设maven将自动使用eclipse中已设置的代理配置。
解决方案是创建/修改settings.xml，并通过以下Eclipse配置步骤对其进行设置：
窗口->首选项-> Maven->用户设置，然后在用户设置输入处配置settings.xml的路径。
我编辑了settings.xml并在其中配置了我的公司代理。
