    Trying to deploy/retrieve/validate the metadata with Ant scripts to sandbox environment and it gives me the below error:

    Error: Failed to login: UNSUPPORTED_API_VERSION - Invalid Api version specified on URL

    Sandbox API version: 36.0

    CustomPackage.xml API version: 36.0 (I did tried with 35 also)
    It is working with another sandbox with APT version 37.0

    Answer:

    I faced same issue and resolved it by downloading similar version ( what my org was having) of ant-salesforce jar file and put that in to lib folder of apache ant folder.

    Here is the below URL you may download

    Note: Here you may put any version number in place of 'nn' in below URL as per your org you are working with

    https://gs0.salesforce.com/dwnld/SfdcAnt/salesforce_ant_nn.0.zip

    for example for for 36.0
    https://gs0.salesforce.com/dwnld/SfdcAnt/salesforce_ant_nn.0.zip
