javac 8 元模型生成错误(hibernate-jpamodelgen) [英] javac 8 error while metamodel generation (hibernate-jpamodelgen)

问题描述

我正在尝试使用 Play Framework 中的 hibernate-jpamodelgen 库自动生成元模型类.

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

我的build.sbt文件是这样的:

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")

虽然 hibernate-jpamodelgen 存在，所有元模型文件都被正确创建，但项目编译失败并出现以下错误:

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

更新:JAVA编译器7存在此错误

UPDATE: This error exists in JAVA compiler 7

推荐答案

编译器插件的特定版本似乎有问题.它不是，因为jdk 或休眠.

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

参考:使用 maven 生成 Hibernate 元模型中的 IllegalStateException.
