Gradle Extended Build Plugin: Can't Call CanRead ()?

I am trying to use Gradle Plugin Advanced Version in my application. I did it as described on the GitHub page:

  • I added this code to my build.gradle app:

    buildscript {
  repositories {
      jcenter()
  }

  dependencies {
      classpath 'org.moallemi.gradle.advanced-build-version:gradle-plugin:1.5.0'
  }
}
apply plugin: 'org.moallemi.advanced-build-version'

  • Then, at the end of the same file, I configured advancedVersioning

    like this:

    advancedVersioning {
    outputOptions {
        renameOutput true
        nameFormat '${projectName}-${buildType}-${versionName}'
    }
}

However, when I do Generate a Signed APK

, I get an error while doing the task :app:assembleRelease

:

Error:

02:06:47.075 [ERROR] [org.gradle.BuildExceptionReporter] 
02:06:47.076 [ERROR] [org.gradle.BuildExceptionReporter] FAILURE:

02:06:47.076 [ERROR] [org.gradle.BuildExceptionReporter]

02:06:47.078 [ERROR] [org.gradle.BuildExceptionReporter] Run with  --stacktrace option to
get the stack trace.

This is on Android Studio 1.3 with gradle plugin 1.2.3. I tried to move the code in step # 1 to Project build.gradle, but I still get the same error.

This seems to be a simple error that causes NullPointerException

.

The versionPropsFile

class property is VersionCodeOptions

initialized only in the getVersionCode

getter.

But the plugin tries to access this property before it calls getVersionCode

, and thus gets a null file reference which fails when it checks if it is canRead()

.

The workaround is pretty simple: all you have to do is make a dummy getter call getVersionCode

right after configuring the plugin, for example:



In the build.gradle project:

advancedVersioning {
    nameOptions {
    }
    codeOptions {
        versionCodeType VersionCodeType.AUTO_INCREMENT_ONE_STEP
        dependsOnTasks 'release'
    }
}

println advancedVersioning.versionCode

After printing out the version code, I call getter and thereby create the file.
