JDT launch configuration classpath [message #259441]

Hi everyone,

I'm having some classpath problems in one of my projects. Generally I'm
using maven (with m2eclipse) as my build tool. However at some point I still
have to use a "conventional" launch configuration for debugging. What I need
to do is to start debugging from a main method in a test-only-purpose
library which depends on some other libraries. So I put everthing in
/src/test/resources/lib and thought I tell the launch configuration to
include that folder in its classpath. Only problem the classloader would not
find anything from that folder. I also tried adding each library explicitely
to the classpath but to no avail :-(
If I put the liraries in my project classpath everything works just fine.

Anybody got a clue what I'm doing wrong?

thx M;chi

Are you creating "conventional" launch configuration for m2e Maven
project by any chance? Can you try to reproduce the problem with "plain"
Java project?

FYI, m2e plays some tricks to insure proper Maven classpath is used to
launch applications and tests from Maven projects. You should be able to
get desired test classpath using dependencies with scope=test in pom.xml.

tried it and it's the same cheese. I simply imported some library with a
static main method into a fresh Java project, created a Java launch
configuration, added that library to the launch configuration classpath (not
the project classpath) and then tried to find the main class from the "Main"
tab of the launch configuration - but had no luck.
btw. I'm running eclipse 3.5M6

that does not work with libraries not present in any repository, or is it?
