I would like to read the versionCode from an external file I am sure that there are any number of possible solutions; here is one: android { compileSdkVersion 18 buildToolsVersion "18.1.0" def versionPropsFile = file('version.properties') if (versionPropsFile.canRead()) { def Properties versionProps = new Properties() versionProps.load(new FileInputStream(versionPropsFile)) def code = versionProps['VERSION_CODE'].toInteger() + 1 versionProps['VERSION_CODE']=code.toString() versionProps.store(versionPropsFile.newWriter(), null) defaultConfig { versionCode code versionName "1.1" minSdkVersion 14 targetSdkVersion 18 } } else { throw new GradleException("Could not read version.properties!") } // rest of android block goes here } This code expects an existing version.properties file, which you would create by hand before the first build to have VERSION_CODE=8.
