could any body please help me on this?

Hi,
What's the java version on you computer, on which you run eclipse? Looks like the subclipse was compiled in a later version and your java version seems to be less then that.

Please check that.

Cheers
Aneesh

hi Aneesh,

i am using java version is jdk1.4

and the svnant.1.2.1.ZIP file.

and the subversion is 1.5.

and i have tortoise client 1.6

coul you please tell me why i am getting this error?

You need to use JDK 5 or 6, the snvant package is compiled with JDK 5.

thanks peter,

now i am getting new proble i.e "[svn] svn: unknown host"

could you help me on this?

Are you sure this is correct URL? Usually there is a port in a subversion URL.

hi jeanne,

thank you for the quick response.

yes, the URL is correct, there is port for this .

http://svn.collab.net/repos/svn/trunk/build/

[svn] svn: connection refused by the server
[svn] svn: OPTIONS request failed on '/repos/svn/trunk/build'
[svn] svn: connection refused by the server
[svn] svn: OPTIONS request failed on '/repos/svn/trunk/build'
[svn] Connection timed out: connect

please lookinto it.

Wait a second, you have now posted 2 different URLs. The link you posted works, but the URL in your build script does not exist.

peter,

by this URl :http://svn.collab.net/repos/svn/trunk/build/

iam trying to cehckout the code , at that time i am getting the above error?

please check with above URL?

is there any issues with proxy setting?

You can easily check the URL yourself - enter it into a browser and see what you get. The URL looks good to me.

Do you use a proxy within your browser to access the internet?

peter,

is it mandatory that svn commandlined lines should execute ? , because i am unable run svn command in my command prompt.

if it is mandatory then which is the best suitable one for subversion1.5?

thanking you for your reponses.

What error do you get? Is svn in your path?

And have you installed the subversion client?
