Unable to use Intellij with a generated sources folder

Question

Related question How to configure IntelliJ IDEA and or Maven to automatically add directories with Java source code generated using jaxb2-maven-plugin   I have a custom plugin that generates sources under target generated-sources  Note no toolname here   So I get sources like target generated-sources com mycompany   etc   This format cannot be changed at all  so will I be able to configure Intellij into adding it as a source folder  As of now  I can see that Intellij has added target generated-sources com as the source folder   Please note that I do not have the option of configuring the plugin    UPDATE 1  I do not agree with the fact that I MUST put my generated sources under a tool name folder  It may be a good convention  but if I have only one generator there is no need for me to put it there  Again  in my pom xml I have a resources section which clearly indicates that target generated-sources should be treated as a source folder  This works perfectly fine in Eclipse so I have no idea why Intellij would not respect my settings    TL DR -  When I put target generated-sources in the resource section of pom xml why is Intellij overzealous to add target generated-sources com to the classpath

The fix Go to Project Structure - Modules - Source Folders and find the target generated-sources antlr4 com mycompany - click Edit properties and set Package prefix to com mycompany  This is exactly the reason why we can set Package prefix on source dirs   Different but related problem here

Whoever wrote that plugin screwed up big time  That s not the way to do it   Any workaround would be a huge hack  make the plugin developer aware of his bug   Sorry  that s the only thing to do     OK here s a hack  directly after your plugin s execution  use the antrun plugin to move the directory somewhere else    lt plugin gt       lt artifactId gt maven-antrun-plugin lt  artifactId gt       lt version gt 1 6 lt  version gt       lt executions gt         lt execution gt           lt phase gt process-sources lt  phase gt           lt configuration gt             lt target gt               lt move todir    project build directory  generated-sources toolname com                    overwrite  true  gt                   lt fileset dir    project build directory  generated-sources com   gt               lt  move gt             lt  target gt           lt  configuration gt           lt goals gt             lt goal gt run lt  goal gt           lt  goals gt         lt  execution gt       lt  executions gt   lt  plugin gt    In this example  toolname should be replaced by anything that uniquely identifies the plugin that created the code and com stands for the root of the created packages  If you have multiple package roots  you probably need multiple  lt move gt  tasks   But if the plugin adds the folder as source folder  then you re screwed

The only working condition  after several attempts  was to remove the hidden  idea folder from the root project folder and re-import it from Intellij

Maybe you can add a step to the generate-sources phase that moves the folder

With gradle  the project settings will be cleared whenever you refresh the gradle settings  Instead you need to add the following lines  or similar  in your build gradle  I m using kotlin so   sourceSets       main           java               srcDir    buildDir absolutePath  generated source kapt main

You can just change the project structure to add that folder as a  source  directory   Project Structure   Modules   Click the generated-sources folder and make it a sources folder   Or    lt plugin gt       lt groupId gt org codehaus mojo lt  groupId gt       lt artifactId gt build-helper-maven-plugin lt  artifactId gt       lt version gt 1 4 lt  version gt       lt executions gt           lt execution gt               lt id gt test lt  id gt               lt phase gt generate-sources lt  phase gt               lt goals gt                   lt goal gt add-source lt  goal gt               lt  goals gt               lt configuration gt                   lt sources gt                       lt source gt   basedir  target generated-sources lt  source gt                   lt  sources gt               lt  configuration gt           lt  execution gt       lt  executions gt   lt  plugin gt
