如何在Gradle和Eclipse之间同步Java源和目标?

Gradle具有源兼容性和可设置的TargetCompatibility变量。Eclipse具有JDK兼容性、生成的类文件兼容性和源代码兼容性。

有没有办法自动设置一个和另一个?理想情况下,Gradle内容将由Eclipse内容设置。

编辑:这些内容似乎存储在:org.eclipse.jdt.core.prefs中

编辑2:它们看起来像:

D:\ray\dev\conradapps\printg>cat.settings\org.eclipse.jdt.core.prefs eclipse.preferences.version=1 org.eclipse.jdt.core.compiler.codegen.inlineJsrBytecode=已启用 org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.8 org.eclipse.jdt.core.compiler.compliance=11 org.eclipse.jdt.core.compiler.debug.localVariable=generate org.eclipse.jdt.core.compiler.debug.sourceFile=generate org.eclipse.jdt.core.compiler.problem.AsserteIdentifier=error org.eclipse.jdt.core.compiler.release=disabled org.eclipse.jdt.core.compiler.source=1.8

我可以让它如下工作,但这是一个黑客:)
