How to add JDK ≥ 9 modules as dependencies

[ayanamists]

It's not a bug.

I'm using JDT as a library instead of run a eclipse container, so I can't make use of apis like IJavaProject. Currently, I could set my jar dependencies by ASTParser::setEnvironment function. For example:

parser.setEnvironment(cp, null, null, false);

By including all JARs (especially, rt.jar) in cp, JDT can correctly parse/resolve my java source file. However, since Java 9, the JDK uses modules to distribute the JRE, and there are no longer such JARs as rt.jar.

I found two workarounds:

1. Packing all JRE modules into a jar file.
2. Setting the includeRunningVMBootclasspath flag of setEnvironment to true, so that JDT will use the current JVM's JRE.

However, I want to know if there's way to add a JRE module as a dependency of ASTParser? Just like include rt.jar in the classpath (cp).
