| classpath cycle with pde build [message #100646] |

When I use pde build to do a headless product build, it fails because of a
classpath cycle, if when using the slf4j bundles. There are two bundles
from slf4j that are in use: slf4j-api-1.4.3.jar and slf4j-log4j12-1.4.3.jar.
The api bundle exports org.slf4j, org.slf4j.helpers and org.slf4j.spi. It
exports org.slf4j.impl. The slf4j-log4j bundle does exactly the opposite.
Therefore there is a bi-directional dependency between the bundles, but not
between the packages, and they are using Import/Export-Package headers, so
this should work fine. However, I get this message:
.. . . genericTargets.xml:85: A cycle was detected when generating the
classpath com.syntellect.vxmlstats.gateway_1.0.0,
com.syntellect.vxmlstats.db_1.0.0, slf4j.api_1.4.3, slf4j.log4j12_1.4.3,
slf4j.api_1.4.3.
Thanks,
Paul

So I am running into this same issue. Has a work around been resolved??? Is this just an Equinox issue? Any help here would be much appreciated. I read the above Bug issue but it seems as if there has been no resolution to this issue.
I can successfully run my RCP Application via the Eclipse Application Run Dialog with all the required plug-ins including SLF4J-API and SLF4J-log4j but when I attempt to export the product with the Product export wizard It fails with the following::
Problems during export
A cycle was detected when generating the classpath org.dcm4che2.core.bundle_2.0.12, slf4j.api_1.4.3, slf4j.log4j12_1.4.3, slf4j.api_1.4.3.
I am assuming for the same reasons stated above. Someone out there has to have a resolution for this since I know of a bunch of project that use SLF4J logging with there Equinox projects...
Please help!!!!
