IntelliJ running wrong version of SpringBoot - mvn and java jar work correctly

Question

I am running version 2018.1.2 of IntelliJ. Whenever I run or debug my application from within IntelliJ, Springboot is running version 2.0.0.RELEASE (and erroring out). The pom.xml has the following set:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.1.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

When I run mvn clean package , I can see that it is running version 2.0.1.RELEASE and everything works as expected. I have also tried running java -jar app.jar and it is showing 2.0.1.RELEASE.

I have looked all over IntelliJ to see if there are any additional settings or places to override the version and I have found nothing. Does anyone know how to ensure the version of Springboot within IntelliJ?

Answer 1

I'm not sure what the actual fix is, but I can provide the steps that resolved the issue:

• Backed up and deleted .idea folder and .iml file from project
• Reimported, build (errored immediately)
• Restored .idea folder, but deleted contents of library folder
• Reimported, mvn clean package, build (failed immediately)
• Restored library items
• Build (failed immediately)
• Mvn clean package, reimport, build (success)

None of the files or steps really changed, but this process somehow fixed things.
