我怎样才能 运行 来自 SBT 的 DataNucleus Bytecode Enhancer？
How can I run DataNucleus Bytecode Enhancer from SBT?
我整理了一个概念证明，旨在提供一个骨架 SBT 多模块项目，该项目利用 DataNucleus JDO Enhancer 以及混合 Java 和 Scala 源。
当我尝试从 SBT 增强持久性 类 时出现困难。显然，从 SBT 调用 Fork.java.fork(...) 时，我没有传递正确的类路径 。
另见这个问题：

来自你的 poc 项目可能是这样的：

然后您需要将 DataNucleus Enhancer 作为构建过程的一部分进行连接。这是通过 manipulateBytecode 子任务完成的，如下所示：
lazy val model =
project.in(file("model"))
// .settings(publishSettings:_*)
.settings(librarySettings:_*)
.settings(paranoidOptions:_*)
.settings(otestFramework: _*)
.settings(deps_tagging:_*)
//-- .settings(deps_stream:_*)
.settings(deps_database:_*)
.settings(
Seq(
// This trick requires SBT 0.13.8
manipulateBytecode in Compile := {
val previous = (manipulateBytecode in Compile).value
sbtRunner( // javaRunner also works!
mainClass = "javax.jdo.Enhancer",
args =
Seq(
"-v",
"-pu", "persistence-h2",
"-d", (classDirectory in Compile).value.absolutePath),
classpath =
(managedClasspath in Compile).value.files ++
(unmanagedResourceDirectories in Compile).value :+
(classDirectory in Compile).value,
cwd = (classDirectory in Compile).value,
javaHome = javaHome.value,
envVars = (envVars in Compile).value
)

}

outputStrategy = outputStrategy,
bootJars = Seq.empty,
workingDirectory = Option(cwd),
runJVMOptions = jvm_,
connectInput = connectInput,
envVars = envVars)
val process = new Fork("java", Option(mainClass)).fork(options, args)
def cancel() = {
println("Run canceled.")
process.destroy()

}
val errno = try process.exitValue() catch { case e: InterruptedException => cancel() }
if(errno==0) {
if (args.contains("-v")) cwd.list.foreach(f => println(f))

}
然后您需要将 DataNucleus Enhancer 作为构建过程的一部分进行连接。这是通过 manipulateBytecode 子任务完成的，如下所示：
lazy val model =
project.in(file("model"))
// .settings(publishSettings:_*)
.settings(librarySettings:_*)
.settings(paranoidOptions:_*)
.settings(otestFramework: _*)
.settings(deps_tagging:_*)
//-- .settings(deps_stream:_*)
.settings(deps_database:_*)
.settings(
Seq(
// This trick requires SBT 0.13.8
manipulateBytecode in Compile := {
val previous = (manipulateBytecode in Compile).value
sbtRunner( // javaRunner also works!
mainClass = "javax.jdo.Enhancer",
args =
Seq(
"-v",
"-pu", "persistence-h2",
"-d", (classDirectory in Compile).value.absolutePath),
classpath =
(managedClasspath in Compile).value.files ++
(unmanagedResourceDirectories in Compile).value :+
(classDirectory in Compile).value,
cwd = (classDirectory in Compile).value,
javaHome = javaHome.value,
envVars = (envVars in Compile).value
)
previous
}
):_*)
.dependsOn(util)
