P ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYWU5MjFjMzE2... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-13949?atlOrigin=eyJpIjoiYWU5Mj... ) HHH-13949 ( https://hibernate.atlassian.net/browse/HHH-13949?atlOrigin=eyJpIjoiYWU5Mj... ) Hibernate doesn't generate metamodel for JPMS module ( https://hibernate.atlassian.net/browse/HHH-13949?atlOrigin=eyJpIjoiYWU5Mj... ) Change By: P ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) I don't know if it bug, but I asked this question on SO [here|https://stackoverflow.com/questions/61233419/is-it-possible-to-gener... got no answer. I have a java module with JPA entities and persistence.xml and I want to generate metamodel with Java 11. I tried two variants. *Variant 1* {code:java} <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.1</version> <configuration> <source>${maven.compiler.source}</source> <target>${maven.compiler.target}</target> <annotationProcessorPaths> <annotationProcessorPath> <groupId>org.hibernate</groupId> <artifactId>hibernate-jpamodelgen</artifactId> <version>5.4.14.Final</version> </annotationProcessorPath> <path> <groupId>javax.xml.bind</groupId> <artifactId>jaxb-api</artifactId> <version>2.3.0</version> </path> <path> <groupId>javax.annotation</groupId> <artifactId>javax.annotation-api</artifactId> <version>1.3.1</version> </path> </annotationProcessorPaths> </configuration> <dependencies> </dependencies> </plugin> {code} Result: {code:java} Caused by: java.lang.NullPointerException at org.hibernate.jpamodelgen.ClassWriter.writeGeneratedAnnotation(ClassWriter.java:202) at org.hibernate.jpamodelgen.ClassWriter.generateBody(ClassWriter.java:100) at org.hibernate.jpamodelgen.ClassWriter.writeFile(ClassWriter.java:53) at org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor.createMetaModelClasses(JPAMetaModelEntityProcessor.java:145) at org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor.process(JPAMetaModelEntityProcessor.java:135) at jdk.compiler/com.sun.tools.javac.processing.JavacProcessingEnvironment.callProcessor(JavacProcessingEnvironment.java:972) at jdk.compiler/com.sun.tools.javac.processing.JavacProcessingEnvironment.discoverAndRunProcs(JavacProcessingEnvironment.java:888) at jdk.compiler/com.sun.tools.javac.processing.JavacProcessingEnvironment$Round.run(JavacProcessingEnvironment.java:1214) at jdk.compiler/com.sun.tools.javac.processing.JavacProcessingEnvironment.doProcessing(JavacProcessingEnvironment.java:1326) at jdk.compiler/com.sun.tools.javac.main.JavaCompiler.processAnnotations(JavaCompiler.java:1258) at jdk.compiler/com.sun.tools.javac.main.JavaCompiler.compile(JavaCompiler.java:936) at jdk.compiler/com.sun.tools.javac.api.JavacTaskImpl.lambda$doCall$0(JavacTaskImpl.java:104) at jdk.compiler/com.sun.tools.javac.api.JavacTaskImpl.handleExceptions(JavacTaskImpl.java:147) ... 28 more {code} *Variant 2* {code:java} <plugin> <groupId>org.bsc.maven</groupId> <artifactId>maven-processor-plugin</artifactId> <version>3.3.3</version> <executions> <execution> <goals> <goal>process</goal> </goals> <phase>generate-sources</phase> <configuration> <compilerArguments>-AaddGeneratedAnnotation=false</compilerArguments> <processors> <processor>org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor</processor> </processors> </configuration> </execution> </executions> <dependencies> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-jpamodelgen</artifactId> <version>5.4.14.Final</version> </dependency> </dependencies> </plugin> {code} Result a lot of errors like the following: {code:java} [ERROR] diagnostic: /home/<deleted>/src/main/java/module-info.java:11: error: module not found: org.slf4j requires org.slf4j; ^ [ERROR] diagnostic: /home/<deleted>/src/main/java/module-info.java:15: error: module not found: java.persistence requires java.persistence; ^ {code} It seems that hibernate metamodel generator can't work with JPMS modules. Either I do something wrong.
