Dependency error when building Ant Script

hello,
I recently migrated from 6 to 7.3 but since I wasn’t able to install the 7 plugin via eclipse (network security) I created a dynamic Web Project and replaced the jars manually. All went well and my application is working great using the 7 libraries and add-ons

Now I want to create an ANT script for my newly migrated project, so I followed the instructions in the “Download” Page, configured my build.properties file and added it, with the others, to my project build path.

although when i run the build.xml as ANT build it gave me the following error

does anyone have an idea how I could resolve this?

Thanks in advance

My first guess would be that you have received a corrupted/truncated version of a JAR, causing the SHA1 verification to fail. Try cleaning your Ivy cache or at least Vaadin related directories in it.

I coudln’t find the option to clean all the cache when I right click on the ivy.xml so I went to the directory on my machine (user/me/.ivy2/cache) and deleted all the files in there. When I ran the build script again it gave me the same error

impossible to resolve dependencies:
    resolve failed - see output for details

and when I click on details it takes me to line 8 from the build.xml

    <ivy:resolve file="ivy.xml" />
