echo keyPassword=\${{ secrets.KEY_STORE }} > ${{env.PROPERTIES_PATH}}

why do you need to put \ after = ?
my build fails here saying:
line 2: syntax error near unexpected token )'`

maybe because I have these characters KEY_STORE

The backslash b4 the = is for escaping the subsequent character.
Are u changing something? I've never had your problem.

yes, I ended up restoring the whole key.properties from base64, similar to how you did key.jks
so instead of 4 concatenating lines I have one,

Thank you for this snippet though, after some adjustment I get it building in CI
