【问题描述】：
我正在处理这个问题。我有一个 maven 项目女巫工作正常，直到我尝试添加一些 junit 依赖项，所以检测到这个依赖项但没有下载，所以我不得不手动下载和安装。直到这里 netbeans 看起来不错，但是当我运行时出现此错误：
Failed to execute goal on project project: Could not resolve dependencies for project ar.com.project:project:jar:1.0-SNAPSHOT: Failed to collect dependencies for [org.springframework:spring-web:jar:3.2.2.RELEASE (compile), com.google.code.gson:gson:jar:1.2.2 (compile), junit:junit:jar:4.11-redhat-1 (test)]: Failed to read artifact descriptor for org.hamcrest:hamcrest-core:jar:1.3-redhat-1: Failure to find org.hamcrest:hamcrest-parent:pom:1.3-redhat-1 in http://maven.repository.redhat.com/techpreview/all was cached in the local repository, resolution will not be reattempted until the update interval of jboss-ga-repository has elapsed or updates are forced -> [Help 1]
To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.

如果你去https://cwiki.apache.org/confluence/display/MAVEN/DependencyResolutionException 并阅读评论，看起来肠道有我同样的问题，我的解决方案是添加 -U 选项，但我找不到哪里：s。你知道在哪里吗？
最好的问候！
