Kotlin 文件夹未检测为 Maven Eclipse 中的源文件夹，sts

Question

如图所示，我在主文件夹中创建了一个文件夹koltin，并将源目录设置为pom.xml 中的该文件夹。但是 kotlin 仍然没有检测为源文件夹。正如您在这个项目的顶部所看到的。其他源文件夹检测正常。

1. src/main/java
2. src/main/resources
3. src/test/java
4. src/test/resources
5. src/main/kotlin ------>这个不见了，应该在这里。

尝试将以下插件添加到您的 pom 文件中。请注意，测试编译也可以显示src/test/kotlin。

<plugin>
    <artifactId>kotlin-maven-plugin</artifactId>
    <groupId>org.jetbrains.kotlin</groupId>
    <version>${kotlin.version}</version>
    <executions>
        <execution>
            <id>compile</id>
            <goals>
                <goal>compile</goal>
            </goals>
            <configuration>
                <sourceDirs>
                    <sourceDir>${project.basedir}/src/main/kotlin</sourceDir>
                    <sourceDir>${project.basedir}/src/main/java</sourceDir>
                </sourceDirs>
            </configuration>
        </execution>
    </executions>
</plugin>
