我從pom.xml 中的檔案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訊息：
$ 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檔案夾？為什么 maven 沒有決議插件中的配置指令？
uj5u.com熱心網友回復：
執行特定 maven 目標的完整命令語法是：
mvn <plugin>:<goal>@<executionId>
當沒有指定 executionId 時，它default-cli默認等于。
現在您執行mvn resources:copy-resources這等效于mvn resources:copy-resources@default-cli但您pom.xml沒有為此目標定義此執行 ID。所以它抱怨一些引數丟失并且沒有配置好。
當您將執行 id 定義為 時copy-resources，這意味著您應該執行：
mvn resources:copy-resources@copy-resources
或者，當您將此目標系結到validate階段時，這意味著您也可以通過以下方式簡單地執行它：
mvn validate
