maven编译kotlin和java混合项目的代码出错

要想编译混合代码应用程序，必须在 Java 编译器之前调用 Kotlin 编译器。
按照 maven 的方式，这意味着应该使用以下方法在 maven-compiler-plugin 之前运行 kotlin-maven-plugin，确保 pom.xml 文件中的 kotlin 插件位于 maven-compiler-plugin 上面，如下：

<plugins>
            <!-- Compiler 插件, 设定JDK版本 -->
            <plugin>
                <groupId>org.jetbrains.kotlin</groupId>
                <artifactId>kotlin-maven-plugin</artifactId>
                <version>${kotlin.version}</version>
                <executions>
                    <execution>
                        <id>compile</id>
                        <phase>compile</phase>
                        <goals>
                            <goal>compile</goal>
                        </goals>
                    </execution>
                    <execution>
