使用Maven通过SSH分发构建文件

Question

我想使用maven的部署生命周期自动上传构建文件。但是，maven似乎无法上传文件。我正在使用Ubuntu 19.04，并且已经设置了paswordless ssh auth wia键。我知道那是行得通的，因为我多次使用它。

Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:version:deploy (default-deploy) on project example: Failed to deploy artifacts: Could not transfer artifact com.example:jar:RELEASE from/to ssh-repository (scpexe://example.com/root): Error executing command for transfer

        <id>ssh-repository</id>
        <url>scpexe://example.com/root</url>
