Build of DC don't start

[Former Member]

Hi,

my Developing Tool is Netweaver Developer Studio 2.0.17 (tryed also 2.0.20, but same Problem).

I've the following problem:

I got a project with several DC's (WebDynpro, Server Component, Externel Library)with Public Parts. The first weeks of the project, building DC was possible and ran. I dont' know what happend, but since one week, the DC-Build-Process don't run anymore. When I start it, a Informationbox (or Errorbox) appears for a very short time (so I'm not able to read the message) and the Build isn't done.

Even a completely new DC isn't builded.

When I try to run the existing build.xml (from the last successful run) directly in ant (Project -> run ant) there are no targets shown and in the ant-dialog I got an error-message concerning the first <taskdef>-tag. Unfortunatly, the error-text is too long and one can't read it completely :-((

If I remove the first <taskdef>-tag the next one causes an error and so on.

I've checked the referenced classes in <takdef>-tags but could not find them, so my idea was that some neccessary classes are missing.

But even a new installation of the Netweaver Developer Studio didn't solve the problem ?!

Does anybody knows a solution???

Thanks

The Problem was solved by opening a SAP-Note, thanks very much to ervin who gave the idea in the right direction.

hi,

Try to remove the DC from the client and from the local system.

Next sync the DC once again.This might help you.

Hi,

sorry, I forgot to describe the development infrastructure: we've no NWDI, I develope the DCs locally. But I deleted the DC from the local System and imported it again. Unfortunally the same problem appear.

Hi,

I could get the hole errormessage whil trying to run the build.xml directly by ant:

There are several classesfiles missing, f.e.

com.sap.dictionary.generation.ant.DDGenAntTask

com.sap.tools.ant.taskdefs.PropertyBag

com.sap.tc.buildplugin.ddic.CreatePPEntitiesInfo

com.sap.tools.ant.taskdefs.Timer

com.sap.webdynpro.generation.ant.WDGenAntTask

com.sap.tools.webdynpro.smart.ClassFileMinimizerTask

com.sap.tools.tc.buildplugin.util.XlfConverter

Maybe it can be some more.

But the build.xml is generated automatically by the IDE, where reside these classfiles normally?

Hi,

the problem is solved: The Build causes an error because of a cyclic DC-Usage-Dependence.

The Build-Error is showed in the Error-Log (Window > Show View > Other ... > PDE runtime > Error Log)

I didn't know this Log-View and as a result I couldn't find the error.

Greeting Thomas
