更改 maven 中資源的目標文件夾

Question

我從我的 pom.xml 中的文檔中復制粘貼了以下片段

  <plugin>
    <!-- <groupId>org.apache.maven.plugins</groupId>-->
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.2.0</version>
    <executions>
      <execution>
        <id>copy-resources</id>
        <phase>validate</phase>
        <goals>
          <goal>copy-resources</goal>
        </goals>
        <configuration>
          <outputDirectory>${basedir}/resources</outputDirectory>
          <resources>                                        
            <resource>
              <directory>${basedir}/template</directory>
              <filtering>true</filtering>
            </resource>             
          </resources>   
        </configuration>            
      </execution>
    </executions>
  </plugin>

但是當我嘗試觸發部署時收到以下消息：

$ mvn resources:copy-resources

這是我的目錄結構：

./resources
./template
./template/test.txt
./pom.xml

如何更改資源的目標文件夾？ 為什么 maven 沒有解析插件中的配置指令？

Answer 1

執行特定 maven 目標的完整命令語法是：

mvn <plugin>:<goal>@<executionId>

不指定 executionId 時，默認等於default-cli 。

現在您執行mvn resources:copy-resources相當於mvn resources:copy-resources@default-cli但您的pom.xml沒有為此目標定義此執行 ID。 所以它抱怨一些參數丟失並且沒有配置好。

當您將執行 ID 定義為copy-resources時，這意味着您應該執行：

mvn resources:copy-resources@copy-resources

或者當您將此目標綁定到validate階段時，這意味着您也可以通過以下方式簡單地執行它：

mvn validate
