I try this mvn configuration ```kotlin   kotlin-maven-plugin   org.jetbrains.kotlin   ${kotlin.version}         ${project.basedir}/src/main/resources/org/springframework/jdbc/core/annotations.xml   ${project.basedir}/src/main/resources/org/springframework/jdbc/core/namedparam/annotations.xml       ``` The Kotlin version is 0.6.800 (But I try with other versions too) But always I get this error ```kotlin [INFO] Using kotlin annotations from /Users/mario/.m2/repository/org/jetbrains/kotlin/kotlin-jdk-annotations/0.6.800/kotlin-jdk-annotations-0.6.800.jar:/Users/mario/IdeaProjects/KotlinProjects/KotlinPrimavera __/KotlinPrimavera/jdbc/src/main/resources/org/springframework/jdbc/core/annotations.xml:/Users/mario/IdeaProjects/KotlinProjects/KotlinPrimavera__ /KotlinPrimavera/jdbc/src/main/resources/org/springframework/jdbc/core/namedparam/annotations.xml [ERROR] java.lang.IllegalStateException: @NotNull method org/jetbrains/jet/utils/PathUtil.jarFileOrDirectoryToVirtualFile must not return null      at org.jetbrains.jet.utils.PathUtil.jarFileOrDirectoryToVirtualFile(PathUtil.java:144)      at org.jetbrains.jet.cli.jvm.compiler.JetCoreEnvironment.addExternalAnnotationsRoot(JetCoreEnvironment.java:151)      at org.jetbrains.jet.cli.jvm.compiler.JetCoreEnvironment.(JetCoreEnvironment.java:120)      at org.jetbrains.jet.cli.jvm.K2JVMCompiler.doExecute(K2JVMCompiler.java:147)      at org.jetbrains.jet.cli.jvm.K2JVMCompiler.doExecute(K2JVMCompiler.java:48)      at org.jetbrains.jet.cli.common.CLICompiler.exec(CLICompiler.java:131)      at org.jetbrains.kotlin.maven.KotlinCompileMojoBase.execute(KotlinCompileMojoBase.java:202)      at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:101)      at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:209)      at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:153)      at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:145)      at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:84)      at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:59)      at org.apache.maven.lifecycle.internal.LifecycleStarter.singleThreadedBuild(LifecycleStarter.java:183)      at org.apache.maven.lifecycle.internal.LifecycleStarter.execute(LifecycleStarter.java:161)      at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:320)      at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:156)      at org.apache.maven.cli.MavenCli.execute(MavenCli.java:537)      at org.apache.maven.cli.MavenCli.doMain(MavenCli.java:196)      at org.apache.maven.cli.MavenCli.main(MavenCli.java:141)      at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)      at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)      at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)      at java.lang.reflect.Method.invoke(Method.java:597)      at org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced(Launcher.java:290)      at org.codehaus.plexus.classworlds.launcher.Launcher.launch(Launcher.java:230)      at org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode(Launcher.java:409)      at org.codehaus.plexus.classworlds.launcher.Launcher.main(Launcher.java:352)      at org.codehaus.classworlds.Launcher.main(Launcher.java:47)      at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)      at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)      at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)      at java.lang.reflect.Method.invoke(Method.java:597)      at com.intellij.rt.execution.application.AppMain.main(AppMain.java:120) ``` ---

That's the same error message I was getting because of this: [http://youtrack.jetbrains.com/issue/KT-4204](http://youtrack.jetbrains.com/issue/KT-4204) See the post "push to maven" from a few days back. The workaround was to rename a parameter. ---

Stack traces look rather different to me. ---

You should not specify paths to annotation.xml files. Intead, give a path to the root of the annotation structure (the parent of "org" directory): ```kotlin   kotlin-maven-plugin   org.jetbrains.kotlin   ${kotlin.version}         ${project.basedir}/src/main/resources/       ``` Please let me know if it fixes the problem ---

Perfect, works fine
