javac 8 error while metamodel generation (hibernate-jpamodelgen)

问题

I am trying to auto generate metamodel classes using hibernate-jpamodelgen library in Play Framework.

My build.sbt file is like this:

libraryDependencies ++= Seq(
  javaCore,
//  filters,
  cache,
  "org.springframework" % "spring-context" % "4.0.4.RELEASE",
  "org.springframework" % "spring-orm" % "4.0.4.RELEASE",
  "org.springframework" % "spring-jdbc" % "4.0.4.RELEASE",
  "org.springframework" % "spring-tx" % "4.0.4.RELEASE",
  "org.springframework" % "spring-expression" % "4.0.4.RELEASE",
  "org.springframework" % "spring-aop" % "4.0.4.RELEASE",
  "org.springframework" % "spring-test" % "4.0.4.RELEASE" % "test",
  "org.hibernate" % "hibernate-entitymanager" % "4.3.5.Final",
  "org.hibernate" % "hibernate-jpamodelgen" % "4.3.5.Final",
  "cglib" % "cglib" % "2.2.2"
)

javaOptions ++= Seq("-Xmx512M", "-Xmx2048M", "-XX:MaxPermSize=2048M")

//for auto generating jpa model metadata
javacOptions ++= Seq("-s", "app")

While hibernate-jpamodelgen exists,all of metamodel files are created correctly but project compilation fails with following error:

[error] Note: Hibernate JPA 2 Static-Metamodel Generator 4.3.5.Final

UPDATE: This error exists in JAVA compiler 7

回答1:

Its seems to be problem with that particular version of the compiler plugin. And its not because of jdk or hibernate.

Refer this: IllegalStateException in Hibernate metamodel generation with maven.

回答2:

I am facing the same with Maven 3.3.1 (3.0.1 was fine) and Java 1.8.0.40 when I use mvn package repeatedly. I'm used to solve this by mvn clean package. Maybe an alternative for your environment may help before they fix up?
