Reboot required for new jars in /lib?

[barnesjd]

I've noticed that if I add a jar to my application's lib directory, I have to reboot my PC for the classes to resolve.  This occurred while trying to use the postgresql driver jar.  I tried restarting the app, restarting grails, and cleaning the app.  Only an OS reboot fixed it.

My environment:
Grails 2.0.1
Java 1.7.0_02-b13
Windows 7 Home Premium, SP1
Postgresql 9.1

Is this expected behavior?

no, it's not an expected behavior

what happens if you use install-dependency script? and restart grails/app

example: grails install-dependency mysql:mysql-connector-java:5.1.16 --dir=lib

Not at all.  I run windows7 pro, but grails 1.3.7 and jvm6.  I will try your config here in a bit.  You should double check it isn't getting odd permissions and that you can see it from the command prompt without elevated privs

Do you use the command prompt or some other shell?

[Jason Davis]

doing

example: grails install-dependency mysql:mysql-connector-java:5.1.16 --dir=lib

does not address the lib dir problem. Just skirts around it.

Ok, I didn't know that I was supposed to use that install-dependency command.  I thought I could just copy the jars into the lib directory.  Other than avoiding a reboot, why does it need a command rather than just dropping it off like I did?

Running 'grails clean' has worked for me.
