Hi Andrew,

I fixed as suggested by Janet and it worked.

JAR_PACKAGES = org.jlab.AutoLogEntry
instead of JAR_INPUT = ...

But, the problem of organization of java applications still remains.

Yes, at least in my case there are no applications to use CA or some

other library from EPICS.

And, I would bet most of people will create Java applications those

would not require to be strictly coupled to EPICS via linking to

libca.so for example.

But, it would be nice to have some way of organization of java applications.

For example $(TOP)/javalib to store all jar and class files seems good

idea.

Then some simple script could easily locate the jar/class files and

execute java command without specifying tons of jar files spread over

different places. Also would be nice to have makeJavaApp.pl for setting

up the initial things.

So, RULES_JAVA is going to removed. That's ok. Maven or ant... that's

fine too.

Is there any recommended scheme for integrating "IDE - development -

version control - building - EPICS directory structure - execution" into

something coherent?

Thanks a lot,
Nerses

Hi Nerses,

Let me ask this way: Is RULES_JAVA supported? Is there any better solution?
What is "standard" build mechanism for EPICS Java application?

RULES_JAVA was written before the more modern Java build tools such as
Maven came along, and our understanding of how Java code is supposed to
be structured may have been mistaken. Janet Anderson who maintains the
build system has been looking into your question and will reply
privately with a suggestion related to using a fully-qualified package
name, but I think Lewis' suggestion that you use another build tool
makes the most sense at this point.

We had already removed RULES_JAVA from the 3.15 version of Base and we
don't know of any of the EPICS Java projects that are using it, so I
think it's safe to say that RULES_JAVA is deprecated and not worth using
any more.
