Execute shell script file to launch mvn command

[Tanyagorn Benjaprompadung]

I already asked this question in stackoverflow via this link https://stackoverflow.com/questions/51424918/izpack-execute-shell-script-file-to-launch-mvn-command
But I think this forum is more active with IzPack users, I decide to post again.

First, I have db_migration.sh with content like this

#!/bin/sh 
eval "mvn compile flyway:migrate"

So, simple. Just want to ease users from executing this command in the terminal by themselves. Due to 'mvn', Of course, this command need to be executed with pom file, which I already place them together in the same directory.

Second, I have this code segment in install.xml file. To mark as executable file after the installation, fix permission denied issue in Unix system

 <executable targetfile="$INSTALL_PATH/Database/orchestra-db/db_migration.sh" os="unix" stage="never" failure="warn" keep="true" />

Then, in the ProcessPanel I have this job to run my db_migration.sh

<job name="do xyz"> 
    <executeForPack name="Orchestra Runtime"/>
    <os family="unix" /> 
    <executefile name="$INSTALL_PATH/Database/orchestra-db/db_migration.sh"> 
        <arg>doit</arg>
    </executefile> 
</job>

However, when I test my installer, I got this error message in the ProcessPanel

Seem like IzPack is looking for pom file and try to execute .sh file in 'target' directory. But, I need this script to be executed at the user's install path. Can anyone tell me what did I do wrong?

Thank you in advance.

You probably have to pass the INSTALL_PATH to your sh script as an argument and in the sh script use the argument to CD to the "right" directory before starting mavens

Exactly like Ron mentioned, you probably launched the installer from the target/ directory which has been taken as working directory, and the pom.xml cannot be found there. This is better then launching it from the directory with the POM just accidentally and call the installer working, and the next call somewhere else fails :-)

You will need to set the execution directory before calling Maven, see also https://izpack.atlassian.net/wiki/x/1oAH.

Approaches:

• Using the workingDir attribute in the ProcessPanel descriptor:
  <executefile name="$INSTALL_PATH/scripts/xyz.bat" workingDir="...">
• In Bash, use $(dirname $0) for getting the directory where the script is actually located
• Use %INSTALL_PATH in your shell script and additionally mark it <parsable> in install.xml
  See https://izpack.atlassian.net/wiki/x/tIAH

Maybe there are more ways, but there should on of the above will be a way to go.

Thanks for your help Ron and Rene.
Especially for describing steps I need to follow in details, and now it works!
Really appreciated.
