java - 为什么我收到 Maven 错误 : "Unable to determine if resource X exists in http://maven.glassfish.org/content/groups/glassfish"?

Question

每当我们在 Maven 中执行我们的 site 目标时，我们都会在控制台日志中得到一长串与依赖关系相关的错误。这些错误似乎是在构建的依赖关系报告创建部分生成的。当根据 http://maven.glassfish.org/content/groups/glassfish 存储库检查资源时，似乎会生成所有错误。 (其中还有一个奇怪的 JavaFX 错误，但我们暂时不用担心)构建成功完成。

我做了一些研究，似乎列出的存储库 URL 是正确的。我想知道这是否可能是我们的 Dependencies 报告插件中的错误？不太确定，欢迎提出建议或猜测

编辑: 针对以下错误之一发布详细的控制台输出:

Answer 1

您需要通过简单地添加 <dependency.locations.enabled>false</dependency.locations.enabled> 来禁用依赖位置检查。在您的pom.xml 的属性部分中接下来:

<properties>
    ...
    <dependency.locations.enabled>false</dependency.locations.enabled>
</properties>

默认值为true更多详情请引用参数 dependencyLocationsEnabled .
