无法计算生成计划-Eclipse Maven

Question

当我尝试构建项目时。生成失败，出现以下消息。

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6

我看到了两个类似的问题，并尝试了答案中提到的一切。

我尝试过的事情。

    <proxies>
        <proxy>
            <id>proxy</id>

            <host>proxy.asdf.com</host>
            <port>6050</port>
        </proxy>
    </proxies>

Answer 1

您写过您的settings.xml位于~.m2/repository中。我想那是不对的。它应该放在~/.m2中。

试着一步一步地解决问题：

确保maven配置正确。将settings.xml放置在~/.m2中。在命令行上，进入项目目录并调用MVN clean Package
