无法在TFS位置建立蚂蚁目标

Question

I have a ant target, xml file in my TFS project folder. the project folder is bound with TFS(Team Foundation Server). My problem is when ever i try to build the project by running the ant target in that TFS bound location it fails. it gives the following failure.

but when i copy the project to a different location and remove the read only attribute from the folder the ant target runs without any error and I'm getting a deploy-able artifact. but even when i remove the read only attribute from the TFS folder i could not build the ant target.It seems like the problem exist on the TFS location it self. :(

can some one suggest me a method to solve this problem. I have to stay in the TFS location you guys know the reason i assume :)

From your question it's hard to figure out what really causes your problem.

Perhabs, your ant call length is too long and even longer than the max command prompt line (that's 8191 characters in the latest versions of Windows). As question Fail to launch application (CreateProcess error=87), can't use shorten classpath workaround says you may consider "to shorten folder names, reduce depth of folder trees, using parameter files, etc".

Try to run ant with the -debug option to see the specific command-line parameters of your build call inside the TFS workspace. In that way you can estimate the total length of the call.
