無法在 org.apache.maven.plugins:maven-dependency-plugin:jar:2.10 收集依賴項

Question

我是第一次使用 eclipse neon，對它了解不多。 我在 POM 中收到此錯誤

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

嘗試檢查您的 Maven 試圖從哪個 Maven 存儲庫服務器下載該軟件包。

它似乎在 Maven Central 上可用： https : //search.maven.org/artifact/org.apache.maven/maven-plugin-api/2.2.1/jar

您可以嘗試將包復制到匹配組路徑下的 ~/.m2/repository 文件夾，看看是否可以解決您的問題作為解決方法。
