Corda - enabling signing on contracts jar causes deployNodes task to fail

Question

I have enabled the signing for contracts module with the following code snippet:

signing {
    enabled true
    options {
        keystore signingKey.keystore
        alias signingKey.alias
        storepass signingKey.storepass
        keypass signingKey.keypass
        storetype signingKey.storetype
    }
}

This works perfectly when I build my contracts with jar task, but when I run the deployNodes task I get the following wired exception:

Execution failed for task ':deployNodes'.
> Corda X.500 names must include an O attribute
   > Corda X.500 names must include an O attribute

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':deployNodes'.

There is nothing interesting in my deployNodes task I guess, but in any case, here it is:

task deployNodes(type: net.corda.plugins.Cordform, dependsOn: ['jar']) {
    nodeDefaults {
        projectCordapp {
            deploy = false
        }
        cordapp project(':tcw-contracts-states')
        cordapp project(':tcw-cordapp')
    }
    node {
        name "O=Notary, L=London, C=GB"
        notary = [validating: false]
        p2pPort 10002
        rpcSettings {
            address("localhost:10003")
            adminAddress("localhost:10043")
        }
    }
    node {
        name "O=PartyA, L=London, C=GB"
        p2pPort 10005
        rpcSettings {
            address("localhost:10006")
            adminAddress("localhost:10046")
        }
        cordapp (project(':tcw_corda_webserver')) {
            config "braidPort=8080"
        }
        extraConfig = [
                'h2Settings.address': 'localhost:10036',
                'dataSourceProperties.dataSource.user': 'asd',
                'dataSourceProperties.dataSource.password': '123'
        ]

        rpcUsers = [[ user: "user1", "password": "test", "permissions": ["ALL"]]]
    }
    node {
        name "O=PartyB, L=New York, C=US"
        p2pPort 10008
        rpcSettings {
            address("localhost:10009")
            adminAddress("localhost:10049")
        }
        cordapp (project(':tcw_corda_webserver')) {
            config "braidPort=8081"
        }
        extraConfig = [
                'h2Settings.address': 'localhost:10039',
                'dataSourceProperties.dataSource.user': 'asd',
                'dataSourceProperties.dataSource.password': '123'
        ]

        rpcUsers = [[user: "user1", "password": "test", "permissions": ["ALL"]]]
    }
}

Answer 1

This error would occur if you had not specified proper value for dname during the time of creation of java key store. It should have "OU=, O=, L=, C=" all supplied properly.

keytool -keystore jarSignKeystore.jks -keyalg RSA -genkey -dname "OU=, O=, L=, C=" -storepass [password] -keypass [password] -alias your-alias

Answer 2

For future references these error is related to the JDK is being used:

Installing with a tooling JDK 8.x works You can do that by installing :

sdk install java 8.0.292-open

BEFORE

Strict rules and SDK might not be the path forward for this tool but .. in this case works

Enjoy. Happy Coding.

Answer 3

similar to Sneha I tried enabling key signing on an example cordapp and was able to run it multiple times locally without any issues.

without being able to see your code here are my suggestions.

try clearing your gradle cache.

try recopying your project to a different directory and with intellij, open the project. (remember open and import project are NOT the same thing).

Make sure your deployNodes task works correctly for other projects on this machine or others.

thanks and best of luck.
