我正在使用带有 play2 的 java8，具有这种配置。
name := """shipping"""
version := "1.0-SNAPSHOT"
lazy val root = (project in file(".")).enablePlugins(PlayJava)
scalaVersion := "2.11.1"
libraryDependencies ++= Seq(
javaJdbc,
javaEbean,
cache,
javaWs,
"org.apache.axis" % "axis" % "1.4",
"net.sf.barcode4j" % "barcode4j" % "2.1",
"xml-apis" % "xml-apis" % "1.4.01",

"wsdl4j" % "wsdl4j" % "1.6.2",
"org.apache.xmlgraphics" % "fop" % "1.0"
)
javacOptions ++= Seq("-source", "1.8", "-target", "1.8", "-Xlint")
LessKeys.compress := true
initialize := {
val _ = initialize.value
if (sys.props("java.specification.version") != "1.8")
sys.error("Java 8 is required for this project.")
}
它有效，但在启动时我收到以下异常。

最佳答案
问题是您不能在像 lambdas 这样的 play 2.3 类模型中使用任何 java 8 功能，因为 ebean ASM 不理解字节码。
我们需要等待播放新版本，但在路线图中，在下一版本中播放将采用JPA而不是ebean
