java kotlin混合变成java编译提示找不到符号

有一个项目，kotlin写了一些逻辑代码，我想加一个controller，新增了一个kotlin方法复用了之前的逻辑，写好之后没有重新编译，直接启动进行测试，整体完全正常没有报错，但是在mvn clean,然后再mvn compile的时候发生了报错，报的是找不到符号，有两个地方，一个是import语句中的kotlin类名，一个是@Resource注入(kotlin类加了@Component注解，交给spring管理了)时候的类名找不到符号。但是IDEA没有标红，点击也可以正常跳转到KOTLIN类文件内，就很奇怪，网上找了不少方法，说是需要先编译kotlin再编译java就能解决，于是修改了pom文件，改成如下顺序，并且需要加上才可以

但是编译后看控制台输出：

仍旧是先编译的java，再次查询资料，修改pom文件如下：

注意看这两处区别：

java 复制代码

<phase>process-sources</phase>
<phase>process-test-sources</phase>

修改后编译就发现kotlin在前边先编译，没有报错了，解决问题！
