解決umi+maven打包的問題

umi是阿里的一個 前端框架，maven想要打包umi框架，必須要用到一個maven插件frontend-maven-plugin。但是不知道爲什麼在我的本地指定outputPath輸出路徑時並沒有生效。還是輸出到umi的默認打包路徑/dist

build --outputPath ${project.build.outputDirectory}/META-INF/resources

maven配置如下：👇👇👇

<build>
        <plugins>
            <plugin>
                <groupId>com.github.eirslett</groupId>
                <artifactId>frontend-maven-plugin</artifactId>
                <version>1.8.0</version>
                <configuration>
                    <npmRegistryURL>https://registry.npm.taobao.org</npmRegistryURL>
                </configuration>
                <executions>
                    <execution>
                        <phase>generate-sources</phase>
                        <id>install node and yarn</id>
                        <goals>
                            <goal>install-node-and-yarn</goal>
                        </goals>
                        <configuration>
                            <nodeVersion>v10.16.2</nodeVersion>
                            <yarnVersion>v1.17.3</yarnVersion>
                            <nodeDownloadRoot>https://npm.taobao.org/dist/</nodeDownloadRoot>
                            <yarnDownloadRoot>https://npm.taobao.org/mirrors/yarn/</yarnDownloadRoot>
                        </configuration>
                    </execution>
                    <execution>
                        <phase>generate-sources</phase>
                        <id>yarn install</id>
                        <goals>
                            <goal>yarn</goal>
                        </goals>
                        <configuration>
                            <arguments>install</arguments>
                        </configuration>
                    </execution>
                    <execution>
                        <phase>generate-sources</phase>
                        <id>yarn build</id>
                        <goals>
                            <goal>yarn</goal>
                        </goals>
                        <configuration>
                            <arguments>build --outputPath ${project.build.outputDirectory}/META-INF/resources</arguments>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

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

爲了解決這個問題，我採用了一種折中的方法，在umi的配置文件.umirc.ts中去指定outputPath的輸出路徑。最終終於實現了maven統一打包umi頁面。

outputPath: "./src/main/resources"
