javakotlin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

<build> <finalName>${project.artifactId}</finalName> <plugins> <plugin> <groupId>org.jetbrains.kotlin</groupId> <artifactId>kotlin-maven-plugin</artifactId> <version>1.9.22</version> <configuration> <jvmTarget>1.8</jvmTarget> <compilerPlugins> <plugin>lombok</plugin> </compilerPlugins> <pluginOptions> <option>lombok:config=${project.basedir}/lombok.config</option> </pluginOptions> </configuration> <dependencies> <dependency> <groupId>org.jetbrains.kotlin</groupId> <artifactId>kotlin-maven-lombok</artifactId> <version>1.9.22</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.22</version> <scope>compile</scope> </dependency> </dependencies> <executions> <execution> <id>compile</id> <phase>compile</phase> <goals> <goal>compile</goal> </goals> </execution> <execution> <id>test-compile</id> <phase>test-compile</phase> <goals> <goal>test-compile</goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.1</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-deploy-plugin</artifactId> <configuration> <skip>true</skip> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-install-plugin</artifactId> <configuration> <skip>true</skip> </configuration> </plugin> </plugins> </build>

但是编译后看控制台输出：

[INFO] [INFO] --- maven-enforcer-plugin:1.4.1:enforce (default-cli) @ --- [INFO] [INFO] --- maven-enforcer-plugin:1.4.1:enforce (banDuplicateClasses-Check) @ --- [INFO] [INFO] --- maven-enforcer-plugin:1.4.1:enforce (check-commons-db-upgrade) @ --- [INFO] [INFO] --- jacoco-maven-plugin:0.7.1.201405082137:prepare-agent (pre-unit-test) @ --- [INFO] argLine set to -javaagent:/***/org.jacoco.agent-0.7.1.201405082137-runtime.jar=destfile=/***/target/jacoco.exec,excludes=org/sqlite/SQLite [INFO] [INFO] --- maven-resources-plugin:2.6:resources (default-resources) @ --- [INFO] Using 'UTF-8' encoding to copy filtered resources. [INFO] Copying 6 resources [INFO] [INFO] --- maven-compiler-plugin:3.8.1:compile (default-compile) @ ---

仍旧是先编译的java，再次查询资料，修改pom文件如下：

<build> <finalName>${project.artifactId}</finalName> <plugins> <plugin> <groupId>org.jetbrains.kotlin</groupId> <artifactId>kotlin-maven-plugin</artifactId> <version>1.9.22</version> <configuration> <jvmTarget>1.8</jvmTarget> <compilerPlugins> <plugin>lombok</plugin> </compilerPlugins> <pluginOptions> <option>lombok:config=${project.basedir}/lombok.config</option> </pluginOptions> </configuration> <dependencies> <dependency> <groupId>org.jetbrains.kotlin</groupId> <artifactId>kotlin-maven-lombok</artifactId> <version>1.9.22</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.22</version> <scope>compile</scope> </dependency> </dependencies> <executions> <execution> <id>compile</id> <phase>process-sources</phase> <goals> <goal>compile</goal> </goals> </execution> <execution> <id>test-compile</id> <phase>process-test-sources</phase> <goals> <goal>test-compile</goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.1</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-deploy-plugin</artifactId> <configuration> <skip>true</skip> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-install-plugin</artifactId> <configuration> <skip>true</skip> </configuration> </plugin> </plugins> </build>

注意看这两处区别：

<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！
