在org.apache.maven.plugins:maven-dependency-plugin:jar:2.10处收集依赖项失败

Question

我是第一次使用eclipse霓虹灯，我对它了解不多。我在POM中遇到此错误

Execution generate-classpath-file of goal org.apache.maven.plugins:maven-dependency-plugin:2.10:build-classpath failed: Plugin org.apache.maven.plugins:maven-dependency-plugin:2.10 or one of its dependencies could not be resolved: Failed to collect dependencies at org.apache.maven.plugins:maven-dependency-plugin:jar:2.10 -> org.apache.maven:maven-plugin-api:jar:2.2.1 (org.apache.maven.plugins:maven-dependency-plugin:2.10:build-classpath:generate-classpath-file:validate)

Answer 1

尝试检查，您的maven正在尝试从哪个maven存储库服务器下载该包。

它似乎可以在Maven Central上找到：https://search.maven.org/artifact/org.apache.maven/maven-plugin-api/2.2.1/jar

您可以尝试将包复制到匹配组路径下的~/.m2/repository文件夹中，看看这是否解决了您的问题。
