Multi Release JAR files

I just found out about Multi Release JAR files and began to look into it on
my Apache NetBeans 9 installation.

At http://wiki.netbeans.org/NetBeans_9 one can read


NetBens 9 will be released from Apache Software Foundation as new Apache
project. NetBeans is being donated to ASG by Oracle. NetBeans 9 main theme
will be to support this upcoming Java SE 9 release.

   - ...
   - *Multi Release JAR files to be handled properly by NB Java Support*

Did support for Multi Release JAR files made it to ANB9 and if so, how and
where do find it/I set it up for my projects? Or was it a goal for NetBeans
itself and I should handle it manually in my poms?

Best to start a separate thread about this, it's not related to the
multi-release JAR question here. Just start a new thread describing the
problem and point to the GitHub repo so someone can reproduce the problem.

Geertjan,
After a few false starts I have uploaded the simple test case for using a
MR-JAR file as a module.  The Git history shows it being used on the
classpath fist then modified to use the modulepath.

Re: Multi Release JAR files

Posted by Emma Atkinson <em...@gmail.com>.
I don't know if this might add to the discussion.  I have tried build a
simple Java application comprising 2 source files (Main.java and
module-info.java) and have it call the default logger for Log4j2 V2.11.1 to
output a single error message.  Nothing more.  I put the
log4j-api-2.11.1.jar on the Modulepath as shown by Project Properties >
Library > Compile tab.

Log4j2 V2.11.1 is a Multi-release JAR (MR-JAR).  The module-info.class file
is in log4j-api-2.11.1.jar under the folder META-INF/versions/9, which
seems to match what the CachingFileManager expects at line 389.  I am not
sure if I am looking at all the right places.

The Netbeans editor can see the module log4j.api because it appears in the
drop-down menu of completion suggestions and does not have wiggly red line
under it.  My simple test program has a module-info.java file that requires
log4j.api and nothing else.  This bit definitely works as I would expect.

The RMB Clean & Build function eventually generates an error pointing to
the line *requires log4j.api* in my module-info.java.  It generates this
error even if I try to compile the module-info.java file on its own.  It
seems to me that the ant build script cannot find module but the Netbeans
editor can.  Unfortunately, I do not understand ant scripts enough to dig
any deeper.

I have tried building this program under JDK-9, JDK-10 and JDK-11.  My
Netbeans runs on JDK-10.  I am learning how to migrate to modules by trial
and error.  I may have made an error, but if I have, I don't know where.

I hope this is helpful.
Emma

Re: Multi Release JAR files

Apache NetBeans has support for reading multi-release JARs. They can appear
on the classpath (modulepath) and the correct types are used, though note
there is (currently) no support for creating them.

Below is where the reading of multi-release JARs is implemented:

Yes, that's where I got it from. :) Attended Nicolai's talk at jdays this

There's nothing in there specifically about NetBeans, but about Maven -- I
don't believe there's anything special done in this area in NetBeans
itself, but that the support for this feature can be used via Maven.
