Bash variables defined during a step

[Samuel Mutel]

Hello,

I would like to define a variable in shell and to use it.

How can I do this?

For example:

sh "find packages -name internal-* -type d -exec bash -c 'for arg; do export VERSION=\$(grep \${arg##*/} nexus-cicd-versions.txt | cut -d: -f2);sed -i \'s/#VERSION#/${env.VERSION}/g\' \$arg/0/package.json; done' _ {} +"

The content of VERSION is the result of a grep from file. I displayed the variable, it works.

Now I would like to use VERSION in the sed part. But I am not able to get the value of VERSION.

I tried ${env.VERSION}, ${VERSION}, $VERSION, ...

Thanks for your help on this topic.

GString might be a bit crazy to escape some chars, maybe it's worthy to create a sh file somewhere and just call it? Then you get the benefits of being able to call/use it without the need to be in the pipeline itself. 

My two cents

In your case you just need to escape \$VERSION to avoid the GString to be interpolated. 

sh "find packages -name internal-* -type d -exec bash -c 'for arg; do export VERSION=\$(grep \${arg##*/} nexus-cicd-versions.txt | cut -d: -f2);sed -i \'s/#VERSION#/\${VERSION}/g\' \$arg/0/package.json; done' _ {} +"

But again, GString might be a bit tricky when escaping in the sh step within the  jenkins pipeline

So you want the $VERSION you defined in the shell:
The you need to use \$VERSION or \${VERSION} I guess.

Otherwise you would try to use the groovy variable (that probably does not even exist).

Yes it is what I did and I think it is the best way. Thanks.
