I am getting below error when running a target of ANT script. Error message saying that "server certificate verification is failed". Please help how to remove this problem. I am working in Windows XP.

Answer 1

can you try to run svn checkout once manually to your URL https://yoururl/trunk C:ant-1.8.1Test_Checkout using command line and accept certificate.

Or as @AndrewSpear says below

Rather than checking out manually run svn list https://your.repository.url from Terminal (Mac) / Command Line (Win) to get the option to accept the certificate permanently

svn will ask you for confirmation. accept it permanently.

After that this should work for subsequent requests from ant script.
