build.gradle - If else in Gradle scripts -

i have strange behavior in gradle , cannot find way out of it. in gradle.properties file, using checking condition:

//gradle.properties  if ( "${system.property['database_dir']}".compareto('swdb') == 0 ) {     project_database_path=../database/swdb/include     }    else {     project_database_path=../database/include/ } 

i created new task called printproperties , looks this.

//build.gradle task printproperties {     println "${system.properties['database_dir']}".compareto('swdb') == 0     println project_database_path } 

i following output when run printproperties task.

$gradle printproperties -ddatabase_dir=swdb

true

../database/include/

:printproperties up-to-date

build successful

total time: 1.07 secs

it strange task prints true gradle.properties file not evaluate same condition correctly. me this?

your code shall take place in init.gradle script.

you can find documentation here : https://docs.gradle.org/current/userguide/init_scripts.html
