Re: Can jdeps resolve unnecessary dependencies?

Mandy, Thanks for you response. Will I be able to take advantage of jlink's ability to produce subset-only image of the JRE even if I do not use new Java 9 modular jars? In other words if my app.jar and other dependent jars are old java 8 ones and do not have any module descriptors will jlink be

Any word on the updated spec

Hello experts, Now that JDK 9 is feature complete, I was wondering if the JSR 376 has been updated recently. Specifically, I am interested in many of the useful information found in the "State of the Module", such as module graph. Now I understand that the SOTM is an informal document, so

Re: Can jdeps resolve unnecessary dependencies?

Thanks for your responses. So today I did some experimentation with Java 8 jdeps to analyze how my app.jar depends at class level on other jars and eventually individual JRE classes. I would run following command: jdeps -v -P -R -cp lib/* app.jar # where lib/ contains jars that app.jar depends

Re: Can jdeps resolve unnecessary dependencies?

My real question I am in pursuit of answering is this: is it in theory possible to build an automated process that would use jdeps to analyze my app to build a minimal JRE image it would run on? The latter could be done by rewriting rt.jar in Java 8 and using jlink in Java 9. Sent from my

Re: Can jdeps resolve unnecessary dependencies?

jdeps is only doing static analysis and doesn’t inspect reflection usage. It’s possible to build such an automated process but not reliable. Convert the app to modules with explict dependences will ensure reliable configuraton. AFAIK javapackager has a RFE to provide this functionality
