Restore Post Install Script setting on managed package patch

Question

Our managed package had a Post Install Script defined which was working fine.

For some undiagnosed reason (perhaps because we started using SFDX?) the Post Install Script setting was erased in a recent update to our patch development org.

Does anyone know how this setting could have been erased, and/or if there is a way to restore it short of moving to a new major release?

Thanks!

I found a solution for this by manually editing the package.xml in the metadata folder to add the missing settings before running sfdx force:mdapi:deploy

More precisely:

1. Run sfdx force:source:convert --outputdir output --packagename "Package Name"
2. Edit output/package.xml to add <postInstallClass>MyPostInstallClass</postInstallClass> (and other settings for the package) under the top-level <Package> element
3. Run sfdx force:mdapi:deploy --deploydir output

To avoid doing this every time it's also possible to do the install in two steps:

1. Create a deploy directory without specifying the package (as suggested by @Dhanasekaran) and upload it:

   sfdx force:source:convert --outputdir output --rootdir src/my-package sfdx force:mdapi:deploy --deploydir output

2. Upload an overlay with only the package settings

   sfdx force:mdapi:deploy --deploydir config

Where the config directory contains:

• package.xml

  With only the top level settings and the install/uninstall scripts, like:

  <Package xmlns="http://soap.sforce.com/2006/04/metadata"> <fullName>My Package</fullName> <postInstallClass>MyPostInstallClass</postInstallClass> </Package>

• classes

  • MyPostInstallClass.cls
  • MyPostInstallClass.cls-meta.xml

If you are using to convert command with packagename option, try not using that option.

sfdx force:source:convert --rootdir src/force-app --outputdir output
sfdx force:mdapi:deploy --deploydir output
