android - Override Java version when building a Cordova project with gradle -

i trying build cordova project using gradle build tool. in cordova project have own plugin requires java 1.7.

in build.gradle comes cordova java version 1.6. build.gradle:

android {     compileoptions {         sourcecompatibility javaversion.version_1_6         targetcompatibility javaversion.version_1_6     } } 

the build.gradle comes great big warning says generated file should not edited, way customize gradle build step - understand - create build-extras.gradle file.

i have created build-extras.gradle file , tried following:

android {     compileoptions {         sourcecompatibility javaversion.version_1_7         targetcompatibility javaversion.version_1_7     } } 

but not seem work. still error when build project.

error:

> strings in switch not supported in -source 1.6 >         switch (action) { >                 ^   (use -source 7 or higher enable strings in switch) 

can please me figure out how setup gradle make work?

i've been trying solve same problem, , came here hoping find answer! anyway, although there no answer, mention of build-extras.gradle put me on right track, , following works me...so thanks.

to begin thought might try using same syntax you, try work out wrong. far can tell fails because build-extras.gradle file not magically merged build.gradle, instead loaded , executed using gradle apply from approach. , since happens before android closure in process, , android values override our 'extra' values.

(i don't have time delve more need gradle or groovy, apologies if terminology not precise...)

however, work if used postbuildextras() method.

if @ bottom of build.gradle file generated cordova you'll see if such method (i.e., postbuildextras) exists on ext, gets called. since last thing in configuration script guess point of method can use override anything.

i therefore ended build-extras.gradle:

ext.postbuildextras = {     android {         compileoptions {             sourcecompatibility javaversion.version_1_7             targetcompatibility javaversion.version_1_7         }     } } 

i had working quite in investigations kept trying other approaches since suspect technique fail when try have multiple build-extras.gradle files -- which, given we're both talking cordova plugins, likely.

there technique looks promising plugins, use <framework> element in plugin.xml, approach never plugin-specific module load/import/whatever. i'll take @ when plugin #2, technique described above gets me big leap further on morning, again build-extras.gradle clue. ;)
