JDK9 Modules

[Stephen Felts]

In the next few weeks, the options will change to the new format and your build will be broken.

I think I must be misunderstanding your suggestion.


If I do:
export _JAVA_OPTIONS="--add-modules=ALL-SYSTEM --add-exports=java.base/HYPERLINK "http://sun.nio.ch"sun.nio.ch=ALL-UNNAMED"

then:

java -version

reports:
Unrecognized option: --add-modules=ALL-SYSTEM
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

If I do:
export _JAVA_OPTIONS="-Djdk.launcher.addmods=ALL-SYSTEM -Djdk.launcher.addexports.0=java.base/HYPERLINK "http://sun.nio.ch"sun.nio.ch=ALL-UNNAMED"

then:

java -version

reports:
java version "9-ea"
Java(TM) SE Runtime Environment (build 9-ea+123)
Java HotSpot(TM) 64-Bit Server VM (build 9-ea+123, mixed mode)

no GRADLE_OPTIONS
no options.compilerArgs in build.gradle

1. The dagger project compiles and runs
2. The neo4j project compiles and runs
3. a JDK8 project still compiles and run

Good to hear you got this working but just to add to what Stephen said about the system properties. The jdk.launcher.* properties that are you using here are not documented and are meant to be JDK-internal. They will be going away soon and so the above will likely need to change to "--add-modules=ALL-SYSTEM --add-exports=java.base/HYPERLINK "http://sun.nio.ch" \nsun.nio.ch=ALL-UNNAMED". Also as Stephen noted, using ALL-SYSTEM is probably not what you want here, at least not if you only want @Generated.
