Re-run Spring Boot Configuration Annotation Processor to update generated metadata

Question

I ve added    lt dependency gt       lt groupId gt org springframework boot lt  groupId gt       lt artifactId gt spring-boot-configuration-processor lt  artifactId gt       lt optional gt true lt  optional gt   lt  dependency gt    to my pom xml per intellij s request warning   Now I m seeing  Re-run Spring Boot Configuration Annotation Processor to update generated metadata    How do I do what intellij is asking me to do    This link  B 2 Generating your own meta-data using the annotation processor  does not have instructions

Following these instructions worked for me: http://www.mdoninger.de/2015/05/16/completion-for-custom-properties-in-spring-boot.html

That message about having to Re-run the Annotation Processor is a bit confusing as it appears it stays there all the time even if nothing has changed.

The key seems to be rebuilding the project after adding the required dependency, or after making any property changes. After doing that and going back to the YAML file, all my properties were now linked to the configuration classes.

You may need to click the 'Reimport All Maven Projects' button in the Maven pane as well to get the .yaml file view to recognise the links back to the corresponding Java class.

I had the same issue  The problem is that the Spring Boot annotation processor generates the spring-configuration-metadata json file inside your  target classes META-INF folder   If you happen to have ignored this folder in IntelliJ like me  because what the heck  who cares about classes files    the file won t be indexed by your IDE  Therefore  no completion  and the annoying message   Just remove target from the ignore files folders list  located in Settings  gt  Editor  gt  File Types  gt  Ignore files and folders

None of these options worked for me  I ve found that the auto detection of annotation processors to be pretty flaky  I ended up creating a plugin section in the pom xml file that explicitly sets the annotation processors that are used for the project  The advantage of this is that you don t need to rely on any IDE settings    lt plugin gt               lt groupId gt org springframework boot lt  groupId gt               lt artifactId gt spring-boot-maven-plugin lt  artifactId gt           lt  plugin gt           lt plugin gt               lt groupId gt org apache maven plugins lt  groupId gt               lt artifactId gt maven-compiler-plugin lt  artifactId gt               lt version gt 3 7 0 lt  version gt               lt configuration gt                   lt compilerVersion gt 1 8 lt  compilerVersion gt                   lt source gt 1 8 lt  source gt                   lt target gt 1 8 lt  target gt                   lt annotationProcessors gt                       lt annotationProcessor gt org springframework boot configurationprocessor ConfigurationMetadataAnnotationProcessor lt  annotationProcessor gt                       lt annotationProcessor gt lombok launch AnnotationProcessorHider AnnotationProcessor lt  annotationProcessor gt                       lt annotationProcessor gt org hibernate jpamodelgen JPAMetaModelEntityProcessor lt  annotationProcessor gt                   lt  annotationProcessors gt               lt  configuration gt           lt  plugin gt

Having included a dependency on spring-boot-configuration-processor in build gradle  annotationProcessor  quot org springframework boot spring-boot-configuration-processor 2 4 1 quot   the only thing that worked for me  besides invalidating caches of IntelliJ and restarting  is  Refresh button in side panel Reload All Gradle Projects Gradle task Clean Gradle task Build

User · Answer

For me  other answers didn t work  I had to go to open Files and do Invalidate caches and restart on Intellij  After that  everything worked fine again

None of the answers worked for me  If you just want to disable the message  go to Intellij Preferences -  Editor -  General -  Appearance  uncheck  Show Spring Boot metadata panel    However  you can also live with that message  if it does not bother you too much  so to make sure you don t miss any other Spring Boot metadata messages you may be interested in
