Unable to find main class Maven

今天在發項目的時候遇到一個小問題。也就是

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.1.12.RELEASE:repackage (repackage) on project com-api-provider: Execution repackage of goal org.springframework.boot:spring-boot-maven-plugin:2.1.12.

其實出現這個問題的原因挺簡單的，我在外層的pom裏面設置了打包插件

   <build>
        <finalName>${project.artifactId}</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
        <!-- 解決maven打包破壞文件的問題 -->
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
                <excludes>
                    <exclude>**/*.jks</exclude>
                    <exclude>**/*.woff</exclude>
                    <exclude>**/*.woff2</exclude>
                    <exclude>**/*.ttf</exclude>
                    <exclude>**/*.txt</exclude>
                </excludes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>false</filtering>
                <includes>
                    <include>**/*.jks</include>
                    <include>**/*.woff</include>
                    <include>**/*.woff2</include>
                    <include>**/*.ttf</include>
                    <include>**/*.txt</include>
                </includes>
            </resource>
        </resources>
    </build>

但是我的項目裏面其實是有很多單純的工具jar的。所以就會出現這個問題。解決方法也很虎

在運行項目的pom裏面引入這個就行，刪除外層的
