[FIXED] execution default of spring-boot-maven-plugin repackage failed

Issue

I've got a simple project that is doing nothing for now and which is just a simple Spring Boot 2 application which supposed to use java 9.

When I run mvnw clean package over hero-journey folder I get this error

ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.0.0.M5:repackage (default) on project hero-journey-web: Execution default of goal org.springframework.boot:spring-boot-maven-plugin:2.0.0.M5:repackage failed.: RuntimeException ->

It does not provide any particular information about the cause except RuntimeException and that something happen (it seems) on class parsing.

mvn -version looks like this

Solution

It seems I ran into existing issue So I used the solution provided by @wilkinsona to resolve it. I added configuration with mainClass and project was successfully built.

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <mainClass>com.lapots.breed.hero.journey.web.HeroJourneyWebApplication</mainClass>
            </configuration>
        </plugin>
    </plugins>
</build>
