我是 Maven 新手，一直在尝试为我的应用程序创建一个 uber jar。我已经能够包含包含转换器中提到的 application.css （仅当资源标签“不”使用时）但是我有一些资源分散在项目中，路径如下：

/src/main/resources/ui/
/src/main/java/com/xyz/internal/installer

我试图将它们作为资源包含在代码中，但是里面的图像 /src/main/resources/ui/ 包括在内，但其他位置不包括在内。此外，当我不使用资源标签时，jar 中包含“application.css”，否则不包含。

【解决方案1】：

您的 pom.xml 看起来不正确。您将 resource filtering 与 maven shade 插件配置混合在一起。

你应该像下面这样配置你的 pom，

   <build>       
    <resources>         
        <resource>        
            <directory>${project.basedir}/src/main/resources/ui/</directory>
            <filtering>false</filtering>
        </resource>
        <resource>
            <directory>${project.basedir}/src/main/java/xyz/internal/installer/</directory>
            <filtering>false</filtering>
        </resource>
        <resource>
            <directory>${project.basedir}/src/main/java/application</directory>
            <filtering>false</filtering>
        </resource>
    </resources>
    <!... 0ther stuff like dependencies...... >
    <plugins>
     <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>2.3</version>
            <configuration>
                <transformers>
                    <!-- add Main-Class to manifest file -->
                    <transformer
                        implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                        <mainClass>application.Main</mainClass>
                    </transformer>
                    <transformer
                        implementation="org.apache.maven.plugins.shade.resource.IncludeResourceTransformer">
                        <resource>application/application.css</resource>
                            <file>${project.basedir}/src/main/java/application/application.css</file>
                    </transformer>
                </transformers>
            </configuration>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
      </plugins>
   </build>

几分，

我使用了 ${project.basedir} 而不是 testproject/src/... 这是最佳实践，您不应该对项目名称进行硬编码。同样使用 ${project.build.directory} 作为目标目录。见this。
如果要将资源过滤器中指定的资源复制到特定位置，则必须使用copy resource plugin。
include empty directory是复制资源插件的配置之一
