it was my first attempt using gradle and i got some weird problem i never heard of. Google didn't help me too much so i am humbly asking for some help. I started using mapstruct after i got some problems with my dao Recipe after adding annotation entity.

I have 2 dependencies related to mapstruct on my gradle file

implementation 'org.mapstruct:mapstruct:1.5.2.Final'

annotationProcessor 'org.mapstruct:mapstruct-processor:1.5.2.Final'

this is my code error, what is interesting is that code works perfectly, but i can't compile it again. If u need some code i'll be happy to provide, as u can see on the screen i have some code generated, but i'm unsure when and why it stopped working.

Internal error in the mapping processor: java.lang.RuntimeException: javax.annotation.processing.FilerException: Attempt to recreate a file for type recipes.mapper.RecipeMapperImpl    at

    Please provide enough code so others can better understand or reproduce the problem. Commented Aug 3, 2022 at 16:52
  • While it does seem to be lacking without code, this isn't even a problem with the code. I had a project that compiled fine 2 hrs ago, made no changes, and now it can't compile. The answer below explaining how mapstruct creates file in the build dir, is spot on correct. Commented Oct 13, 2023 at 19:44

It seems that you already have a file call RecipeMapperImpl if i look your image.
But the file didn't appear on the left in project explorer.

MapStruct will create a file RecipeMapperImpl so he wont success if one already exist.

I suggest to remove the file RecipeMapperImpl in your project if he still exist and run a clean compile with gradle.

I faced the same error for this reason. Hope it help.

delete file from generated-source and rebuild. This resolved my problem.

I had the same problem when I was using one more plugin for code generation. In my case, it was com.sun.xml.ws:jaxws-maven-plugin:4.0.1, which generates java classes from WSDL. When I changed sourceDestinationDir for jaxws-maven-plugin to new destination {project.baseDir}/target/generated-source/xjc/ (instead of {project.baseDir}/target/generated-source/, it solved my problem.

So try to check if you are not using some different plugin/processor that generates code to the same location as mapstruct.

This was also the case with cxf-codegen-plugin in conjunction with mapstruct. Changing the sourceRoot was the solution.

Try deleting target/ folder and rebuild the project. Worked for me.

This! But if you use maven, do not use mvn clean install, but the Build project of Idea itself.

enter image description here I compiled and worked successfully after that I deleted the generated class 'ObjectConvertorImpl' from the file 'target/generate-sources'

For me in IntelliJ this problem was solved by restarting the IDE with cache invalidation.

After having problems with mapstruct processor and lombok, I tried invalidating the cache and after restarting it compiles correctly.

MapStruct automatically creates in the folder target/generated-sources/... the basic implementation to the methods declared in your interface. Try to delete the .java file autogenerated and compile again.

Try these options for maven plugin "useIncrementalCompilation = false. It worked for me

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>${maven.compiler.source}</source>
                <target>${maven.compiler.target}</target>
                <useIncrementalCompilation>false</useIncrementalCompilation>
