I'm trying to add the following dependency for my plugin:

 implementation( group: 'org.tensorflow', name: 'tensorflow-core-platform', version: '0.4.0')

I am getting the above exception. Can anyone help to resolve this?

Can you share the policy file of that plugin along with the output of unzip -l of the packaged plugin?

Hi @spinscale ,
This is the contents of policy file:

grant {
    permission java.io.FilePermission "/app/models/saved_model/*", "read";
    permission java.lang.RuntimePermission "getClassLoader";
    permission java.lang.RuntimePermission "setContextClassLoader";
    permission java.lang.RuntimePermission "accessDeclaredMembers";
    permission java.util.PropertyPermission "*", "read, write";
};

This is the output of the unzip -l:

Hey,

so I think there might be an issue with the platform specific jars, so that tensorflow-core-api-0.4.0.jar and tensorflow-core-api-0.4.0-linux-x86_64.jar are both summarized as tensorflow-core-api and thus the plugin installer thinks this is a duplicate.

Can you open an issue for this in Issues · elastic/elasticsearch · GitHub

Thanks!
