Several tasks not accessable in build.gradle file in connection with Android Studio -

i found weird behaviour in android studio.

i want access dexdebug task in module build.gradle file.

apply plugin: 'com.android.application'  android {     compilesdkversion 22     buildtoolsversion "22.0.1"      defaultconfig {         applicationid "com.testprj.test"         minsdkversion 10         targetsdkversion 22         versioncode 1         versionname "1.0"     }     buildtypes {         release {             minifyenabled false             proguardfiles getdefaultproguardfile('proguard-android.txt'), 'proguard-rules.pro'         }     } }  dexdebug.dofirst {     // stuff here } 

but following error: error:(rownumber, 0) not find property 'dexdebug' on project ':app'.

that's weird because can call task on android studio terminal via gradle dexdebug.

what reason it?

create own task:

task mytask() {  } 

make task "process stuff" before dexdebug:

gradle.taskgraph.whenready { taskgraph ->      if (taskgraph.hastask(dexdebug)) { // <-- check if task ready         dexdebug.dependson mytask // <-- make depend on task     } }
