Hi Alan,
thanks for the quick reply. Unfortunately I could not get it to work
with --patch-module (I tried before finding -XD-Xmodule).
Maybe I'm doing something wrong? I'm using a JPMS demo project I
developed[1]. I get the expected compilation errors when doing this:
javac --module-path mods -d classes \
monitor.rest/src/main/java/monitor/rest/MonitorServer.java
It works with -XD-Xmodule:
javac --module-path mods -d classes \
XD-Xmodule monitor.rest
monitor.rest/src/main/java/monitor/rest/MonitorServer.java
With --patch-module I get the same errors as without:
javac --module-path mods -d classes \
--patch-module monitor.rest=mods/monitor.rest.jar \
monitor.rest/src/main/java/monitor/rest/MonitorServer.java
Also, it looks like the option is not even really processed. If using
a non-existent module name or JAR or even if I add some additional
equal signs, I get no particular error for that.
I'm on ea-172-Jigsaw.
so long ... Nicolai

it can be built with the contained compile.sh or multi-compile.sh
(maybe after removing the 9's from the commands)
