gradle-android-add-dir
A simple script to help manually inject source or test directories into a .iml file before every build. This is required before every build because .iml files are regenerated before every build.
This is a modified version of a script posted by Bernd Bergler
#Usage
Apply the script at the top of your build.gradle file. Make sure to define the two necessary properties before the script is applied.
| Property | Description |
|---|---|
project.ext['src.java.dir'] |
Takes an array of source directories |
project.ext['module.iml.file'] |
Takes a string with the path to the module's .iml file. |
project.ext['src.java.dir'] = ['src/test/java']
project.ext['module.iml.file'] = "VaDroid3.iml"
apply from: 'gradle-android-add-dir.gradle'
// The rest of the build.gradle script
The script can alternatively be applied directly from it's location on Github.
apply from: 'https://raw.github.com/sababado/gradle-android-add-dir/master/gradle-android-add-dir.gradle'
##Why Use This?
Android Studio dropped the ability to mark your own source directories due to lack of gradle support. One example where this is necessary is when trying to do unit tests using robolectric. The practice is to have a src/test/java directory with unit tests in them. The IDE won't recognize this as a source directory. It can be done by manually updating the module's .iml file however it will be overwritten everytime a build is run.
###android-unit-test
This works very well with the android-unit-test plugin. A simple solution to get all dependencies reading correctly while working on files in src/test/java is to assign dependencies to instrumentTestCompile for build tools 0.8 and below or androidTestCompile if you're using build tools 0.9 or higher and testCompile. Even if they aren't needed in the former (instrument or android) . That is the quickest workaround for some users.
##Is this a hack? Yes. Yes it is. Until Android Studio brings back support to mark your own source directories this will be relevant. ##There has to be a better way... If you find one please let me know so I can stop doing this hack.
