Gradle 4.7 targetCompatibility for JDK 10

Question

Anybody know what targetCompatibility value to use for JDK 10? Supposedly Gradle 4.7 supports it.

e: Currently using 1.10 but I can't find any confirmation that this is correct. java --version reports 10.x instead of the usual 1.x.x format.

Answer 1

Set the Gradle version & Java Version in build.gradle as below

task wrapper(type: Wrapper){
         gradleVersion = '4.7'
     }

sourceCompatibility = JavaVersion.VERSION_1_10
targetCompatibility = JavaVersion.VERSION_1_10

Now, right click the build.gradle->Gradle->Refresh Gradle Project. And check the JRE System Library (Package Explorer view) contains JavaSE-10

Note: I am using Eclipse Oxygen IDE with Gradle IDE plugin.
