Maven Spring Boot Compilation Failed

spring-boot

I am trying to build spring-boot 2.0.0.RELEASE app using maven which will be deployed to Heroku. I am using IntelliJ for development, but maven gives compilation error with command mvn spring-boot:run / mvc clean install.

I am also using Kotlin for data classes and Java for other classes. This is my first time building with maven so I am unable to fix this issue.

The project is available at github

Your Java code is being compiled before your Kotlin code has been compiled. As a result, the Java code that depends on the Kotlin code fails to compile.

The solution is described in Kotlin's documentation. You need to update your pom so that Kotlin compilation is performed before Java compilation by disabling the default Java compilation goals:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <executions>
                <!-- Replacing default-compile as it is treated specially by maven -->
                <execution>
                    <id>default-compile</id>
                    <phase>none</phase>
                </execution>
                <!-- Replacing default-testCompile as it is treated specially by maven -->
                <execution>
                    <id>default-testCompile</id>
                    <phase>none</phase>
                </execution>
                <execution>
                    <id>java-compile</id>
                    <phase>compile</phase>
                    <goals>
                        <goal>compile</goal>
                    </goals>
                </execution>
                <execution>
                    <id>java-test-compile</id>
                    <phase>test-compile</phase>
                    <goals>
                        <goal>testCompile</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
