签署 Corda 工作流 jar 时 Jarsigner 重复输入错误

Question

我尝试为我执行以下命令的 Corda 工作流 jar 签名： jarsigner -keystore test_app_sign.jks -storepass password123 -keypass password123 tcw-workflows.jar test_app_alias

但我收到此错误： jarsigner: unable to sign jar: java.util.zip.ZipException: duplicate entry: META-INF/io.netty.versions.properties

当我对我的 jar jar tf workflows.jar | grep META-INF/io.netty.versions.properties 运行以下命令时，我可以看到里面有 5 个 META-INF/io.netty.versions.properties 文件。

当我运行以下命令查看这些文件的内容时

unzip -p tcw-workflows.jar META-INF/io.netty.versions.properties

我看到以下内容：

所以这些是不同的文件，我想它们都需要在那里，但是它们都具有相同的名称这一事实阻止了 jar 签名者对 jar 进行签名。有什么想法可以解决吗？

附：我的工作流项目有一个依赖 io.bluebank.braid:braid-corda:4.1.1 我猜它依赖于 netty

尝试将以下内容添加到您的build.gradle：

jar {
    exclude '**/io.netty.versions.properties'
}
