使用com.googlecode.maven-download-plugin下載多個工件

我想使用download-maven-plugin從 Maven 存盤庫下載幾個工件

我可以很好地下載一個工件，但是當我添加第二個工件時，它會被忽略：

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

我認為問題在于configuration應該為每個指定execution并且plugin只宣告一次，但這不會編譯：

或者，如果有另一種方法可以從 Maven 存盤庫下載到檔案（特別是需要從settings.xml.

uj5u.com熱心網友回復：

https://maven.apache.org/plugins/maven-dependency-plugin/copy-dependencies-mojo.html似乎是上述問題的更好解決方案。它會：

將專案依賴項從存盤庫復制到定義位置的目標。

你可以運行mvn org.apache.maven.plugins:maven-dependency-plugin:copy-dependencies。這將從您的 POM 中讀取依賴項，settings.xml正常使用并復制它們。我認為默認是一個目錄，target但它是可配置的。
