Thanks Nathan!
Its not that the files are not compiling. our build process does
not give any issues. the problem is coming when the installer tries to
execute liquibase update. Installer works fine incase of clean
install. we are experiencing this incase of upgrade
Following is what the installer is trying to do.
1. remove existing 2.1 liquibase jar
2. copy new 3.1 liquibase jar at the desired location
3. execute liquibase update
Please also note that when we run liquibase update in the command
prompt, it works fine.
I can try with 3.2.x to see how it works.
