IntelliJ with spring-boot-jetty-jsp

I'm trying to run the spring-boot-jetty-jsp sample. It works from the command line using mvn jetty:run but when I try it in IntelliJ I get this error:

Process finished with exit code 1

It is possible to create a maven configuration in IntelliJ and run the jetty:run argument with that configuration, then it works. But what does the above error mean?

It's because the example lists Jetty starter dependency as provided so IntelliJ does not include it in your module, making ServletContext class unavailable, thus causing the NoClassDefFound exception.

Change the definition of spring-boot-starter-jetty dependency in your pom.xml file:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jetty</artifactId>
    <!--<scope>provided</scope>-->
</dependency>

<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>apache-jsp</artifactId>
    <!--<scope>provided</scope>-->
</dependency>

and refresh/reimport the maven project in IntelliJ.

Alternatively, if you do not wish to change the example code, you can manually edit the dependencies in your module's settings in IntelliJ - simply change all Provided dependencies to Compile and it should yield a similar result.
