Maven 2 Maven 3警告：无法传输asm:asm/Maven-metadata.xml

在使用依赖项构建giraph jar时，我们收到以下警告。。真的不知道如何解决这些。。我们已经试过了

将项目工件用作false
和
按真值解包

这两种药似乎都管用

有没有关于如何解决这些问题的建议

这看起来像是连接问题、代理问题或防火墙问题，因此您可以制定以下解决方案：

• 显式引用ASM依赖项。查看正确的版本，并尝试将其添加到pom（）中。之后，执行

  mvn安装

  ，确保一切正常

• 如果不起作用，您可以尝试手动下载依赖项并将其复制到本地存储库（本地文件夹“.m2”）中，可能位于“/.m2/asm/asm/”。这不是最好的解决方案，但也许这可以解决你的问题

希望有帮助

在代理人背后？防火墙？您是否更改了settings.xml？
