ESB type deploy failed for signer-maven-plugin

When I use deploy goal to publish ESB artifacts, I meet an error like [ERROR] Failed to execute goal org.talend.ci:signer-maven-plugin:7.1.1:sign (sign) on project DemoServicePortType_DemoServiceOperation: Artifact [E:\nb\Talend-Studio-20181009_1932-V7.1.1SNAPSHOT\workspace\LOCAL_PROJECT\poms\jobs\process\DemoService\DemoServicePortType\DemoServiceOperation\demoserviceporttype_demoserviceoperation_0.1\target/demoserviceporttype_demoserviceoperation_0_1.zip] does not exist! -> [Help 1], because the artifact is kar/jar extension.
