How to handle shell prompt in maven

问题

I have a pom.xml file that executes a shell script, and the shell script has the prompt

"Enter 'YES' to have this script continue:"

How do I tell maven 1)Parse the prompt, 2)Enter YES when it sees the prompt?

Or at the least, an answer to the second question above?

Thanks.

I had a similar problem. One of my plugins was designed to display some information to user and proceed only after confirmation. When I had to use it on our CI build server, I ended up with this:

echo 'y' | mvn release:branch ...

I assume that you could either go with this approach (if it works for you), or use gmaven plugin to execute Groovy code before the execution of your shell script that would write needed string to system input.

You're using an interactive script in non-interactive mode. The script should have a parameter (ie. --non-interactive, or -y / -n, etc.) which disable the prompt and force the answer.

Setup script run as yes | ./script in pom.xml

I ended up using https://bitbucket.org/atlassian/bash-maven-plugin and had this in my pom.xml file

    <plugin>
        <groupId>com.atlassian.maven.plugins</groupId>
        <artifactId>bash-maven-plugin</artifactId>
        <version>1.0-SNAPSHOT</version>
        <executions>
            <execution>
                <id>execute-shell</id>
                <phase>generate-sources</phase>
                <goals>
                    <goal>run</goal>
                </goals>
                <configuration>
                    <script>./build_dm.sh --accept-warning</script>
                </configuration>
            </execution>
        </executions>
    </plugin>

You could use Expect, writing a wrapper script which, in turn, calls the interactive script.

To install it on Ubuntu:

sudo apt-get install expect

This script should work:

#!/usr/bin/expect

spawn ./test.sh
expect "Enter 'YES' to have this script continue:"
send "YES\r"
interact
