trying jigsaw-ea-95 jlink

[Sebastian Sickelmann]

Hi I am trying to work with jlink, and do not get it working. What I am
doing wrong?

My compiled modules(not jars, but exploded in the filesystem) are at the
directory mymods
I can start my programm via
sebastian at Inspi:~/example1$ ~/jigsaw-ea-95/bin/java -mp mymods -m
demo.app/demo.app.Example1
<output-of-programm>

The mymods directory has the following structure
sebastian at Inspi:~/example1$ du --si mymods
8.2k    mymods/demo.app/demo/app
13k    mymods/demo.app/demo
21k    mymods/demo.app
8.2k    mymods/demo.lib/demo/lib
13k    mymods/demo.lib/demo
21k    mymods/demo.lib
46k    mymods

If i now try to create a distribution with jlink, i add my module
demo.app and declare mymods and the jmod dir as modulepath
sebastian at Inspi:~/example1$ ~/jigsaw-ea-95/bin/jlink --modulepath
mymods:/home/sebastian/jigsaw-ea-95/jmods --addmods demo.app --output
jlink-ea

I can list the modules that are included in the resulting distribution
sebastian at Inspi:~/example1$ jlink-ea/bin/java -listmods
demo.app
demo.lib
java.base at 9-ea

But I am not able to start my programm
sebastian at Inspi:~/example1$ jlink-ea/bin/java -m demo.app/demo.app.Example1
Error: Could not find or load main class demo.app.Example1 in module
demo.app

To be sure not to made a typing error i tried
sebastian at Inspi:~/example1$ jlink-ea/bin/java -m
demo.app.not.existing/demo.app.Example1
Error occurred during initialization of VM
java.lang.module.ResolutionException: Module demo.app.not.existing not found
    at java.lang.module.Resolver.fail(java.base at 9-ea/Resolver.java:860)
    at java.lang.module.Resolver.resolve(java.base at 9-ea/Resolver.java:291)
    at
java.lang.module.Configuration.resolve(java.base at 9-ea/Configuration.java:246)
    at
jdk.internal.module.ModuleBootstrap.boot(java.base at 9-ea/ModuleBootstrap.java:188)
    at java.lang.System.initPhase2(java.base at 9-ea/System.java:1911)

But it seemed that I am not able to type a wrong module name. So there
is no typing error there.

And if I just want to start my module (without a startup-class)
sebastian at Inspi:~/example1$ jlink-ea/bin/java -m demo.app
module demo.app does not have a MainClass attribute, use -m
<module>/<main-class>

It says that java does not find the MainClass (as expected)

What I am doing wrong?

Thanks for your help.
