maven-dependency-plugin不能排除测试范围依赖项

Question

          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>

              </execution>
            </executions>

PS：请不要建议我在这里使用assembly或其他fat-jar插件，因为我有意复制依赖项jar用于Docker映像构建优化：一层用于依赖项，另一层用于jar，在任何依赖项改变之前，依赖项层总是被缓存：

COPY target/dependency  /usr/lib/app/lib
COPY target/${JAR_FILE} /usr/lib/app/target.jar

解决方案可能在IncludeScope描述中：

要包括的范围。空字符串表示所有作用域（默认值）。被解释的作用域是Maven看到的作用域，而不是POM中指定的作用域。总之：

• runtime作用域提供运行时和编译依赖项，
• compile作用域提供编译、提供和系统依赖项，
• test（默认）作用域提供所有依赖项，
• 提供的作用域只提供了提供的依赖项，
• system作用域只提供系统依赖项。
