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 09/16/14 04:57 -ում, Andrew Johnson-ը գրել է:

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. - Andrew
