Gradle build taking too long

Question

Executing tasks: [:app:clean, :app:generateDebugSources, :app:generateDebugAndroidTestSources, :app:prepareDebugUnitTestDependencies, :app:mockableAndroidJar, :app:assembleDebug]

Parallel execution with configuration on demand is an incubating feature. Incremental java compilation is an incubating feature. :app:clean :app:preBuild UP-TO-DATE :app:preDebugBuild UP-TO-DATE :app:checkDebugManifest :app:preReleaseBuild UP-TO-DATE :app:prepareAsiaIvityAndroidMarqueeview115Library :app:prepareComAndraskindlerParallaxviewpagerParallaxviewpager031Library :app:prepareComAndroidSupportAnimatedVectorDrawable2321Library :app:prepareComAndroidSupportAppcompatV72321Library :app:prepareComAndroidSupportMultidex101Library :app:prepareComAndroidSupportRecyclerviewV72321Library :app:prepareComAndroidSupportSupportV42321Library :app:prepareComAndroidSupportSupportVectorDrawable2321Library :app:prepareComGithubTecheryProgresshintLibrary023Library :app:prepareComGithubTecheryProgresshintLibraryAddition023Library :app:prepareComH6ah4iAndroidWidgetVerticalseekbarVerticalseekbar051Library :app:prepareComOgaclejapanSmarttablayoutLibrary160Library :app:prepareComToxicBakeryViewpagerTransformsViewPagerTransforms1232Library :app:prepareDebugDependencies :app:compileDebugAidl :app:compileDebugRenderscript :app:generateDebugBuildConfig :app:mergeDebugShaders :app:compileDebugShaders :app:generateDebugAssets :app:mergeDebugAssets :app:generateDebugResValues UP-TO-DATE :app:generateDebugResources :app:mergeDebugResources :app:processDebugManifest :app:processDebugResources :app:generateDebugSources :app:preDebugAndroidTestBuild UP-TO-DATE :app:prepareComAndroidSupportMultidexInstrumentation101Library :app:prepareDebugAndroidTestDependencies :app:compileDebugAndroidTestAidl :app:processDebugAndroidTestManifest :app:compileDebugAndroidTestRenderscript :app:generateDebugAndroidTestBuildConfig :app:mergeDebugAndroidTestShaders :app:compileDebugAndroidTestShaders :app:generateDebugAndroidTestAssets :app:mergeDebugAndroidTestAssets :app:generateDebugAndroidTestResValues UP-TO-DATE :app:generateDebugAndroidTestResources :app:mergeDebugAndroidTestResources :app:processDebugAndroidTestResources :app:generateDebugAndroidTestSources :app:preDebugUnitTestBuild UP-TO-DATE :app:prepareDebugUnitTestDependencies :app:mockableAndroidJar UP-TO-DATE :app:incrementalDebugJavaCompilationSafeguard :app:compileDebugJavaWithJavac :app:compileDebugJavaWithJavac - is not incremental (e.g. outputs have changed, no previous execution, etc.).

Note: Some input files use or override a deprecated API. Note: Recompile with -Xlint:deprecation for details.

It currently has approximately 11833 MB. For faster builds, increase the maximum heap size for the Gradle daemon to more than 13312 MB. To do this set org.gradle.jvmargs=-Xmx13312M in the project gradle.properties. For more information see https://docs.gradle.org/current/userguide/build_environment.html :app:validateDebugSigning :app:packageDebug :app:zipalignDebug :app:fullDebugBuildInfoGenerator :app:assembleDebug

My problem is solved.It was taking time because i have ubuntu and i was opening and running my project from external ntfs hard drive.I reformatted it as ext4 and followed the given post which reduced the **build time** to **2 sec** from 7 min — user6265154, May 20 '16 at 11:24

The default Gradle Daemon VM memory allocation is 1 gigabyte — which is insufficient to support dexInProcess, so to take advantage you’ll need to set it to at least 2 gigabytes.

One thing you could do to speed up your builds is to increase the Gradle Daemon VM memory allocation.

In gradle.properties add the line org.gradle.jvmargs=-Xmx2048m.

A link to a potential solution is always welcome, but please [add context around the link](http://meta.stackoverflow.com/a/8259/169503) so your fellow users will have some idea what it is and why it’s there. Always quote the most relevant part of an important link, in case the target site is unreachable or goes permanently offline.

Make your gradle offline.

Goto File -> Settings search for gradle and checked offline work .

That's hardly a solution considering you will need it to go online at times – Tim May 17 '16 at 11:55
