Maven JAR插件跳过generated-resources文件夹

标签： angularjs spring maven spring-boot

在尝试运行一个简单的AngularJS Spring Boot项目时（在解决this thread中提到的问题之后），我遇到了一个奇怪的问题。以下是我的Maven POM。我面临的问题是，虽然Wro4j插件能够在 generated-resources 下生成JS / CSS文件，尽管在 build / resources 下我已经提供了要打包的路径， generated-resources 下的文件没有打包到“ static ”文件夹下的JAR中（只显示我的自定义JS文件和index.html文件）那里）。怎么能纠正这个？

在wro4j-maven-plugin:run阶段之后，

compile正在process-resources阶段运行，其中所有资源都被复制到${project.build.outputDirectory}（默认情况下为target/classes）。只有来自此文件夹的文件才会包含在您的JAR中，但您的CSS / JS文件是在 Maven尝试将它们复制到outputDirectory后生成的，因此永远不会被添加。

您只需将Wro4j插件配置为在generate-resources阶段运行：

       <plugin>
            <groupId>ro.isdc.wro4j</groupId>
            <artifactId>wro4j-maven-plugin</artifactId>
            <version>${wro4j.version}</version> 
            <executions>
              <execution>
                <phase>generate-resources</phase>
                <goals>
                  <goal>run</goal>
                </goals>
              </execution>
            </executions>
       ...
       </plugin>

如果由于某些原因导致您的文件无法在compile之前生成（可能需要编译代码），您可以使用Maven Resources插件手动将资源添加到项目构建输出目录中在之后生成，就像您在评论中一样生成 - 但我建议您在prepare-package阶段使用${project.build.outputDirectory}执行此操作，例如：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.0.2</version>
    <execution>
        <id>copy-resources-post-compile</id>
        <phase>prepare-package</phase>
        <goals>
            <goal>copy-resources</goal>
        </goals>
        <configuration>
            <outputDirectory>${project.build.outputDirectory}</outputDir‌​ector‌​y>
            <resources>
                <resource>
                    <directory>${project.build.directory}/generated-res‌​ources</directory>
                </resource>
            </resources>
        </configuration>
    </execution>
</plugin>
