Question

我有一个中等规模的项目，有很多模块相互依赖。当我运行mvn compile或mvn package时，它可以工作，但是当我尝试从根目录运行mvn dependency:tree时，它会失败，抱怨它无法从神器中获取工件。确实神器不存在于神器中。它是我编写的模块之一，是我项目中另一个模块的依赖项。为什么mvn dependency:tree在认识到这是第一方模块时会在神器中搜索此模块？ mvn package不抱怨。请指教。 maven错误就像这样 [ERROR] Failed to execute goal on project XXX: Could not resolve dependencies for project XXX: Could not transfer artifact YYY from/to repo (ZZZ): Failed to transfer file: YYY. Return code is: 503 , ReasonPhrase:Error. -> [Help 1]

如果需要，这是我的settings.xml：

<?xml version="1.0" encoding="UTF-8"?>
<settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd"

Answer 1

'mvn package'跳过Maven周期的'验证'阶段。

这样你就可以成功使用'mvn package'而且你从来不知道任何'验证'问题。

Answer 2

这与Maven doesn't recognize sibling modules when running mvn dependency:tree相同，答案是：

mvn compile dependency:tree
