meteor run android- spawn ENOENT and gradle errors from Cordova

Leave a Comment

I am attempting to run a Meteor project on an Android device and/or emulator. When I run either meteor run --verbose android or meteor run --verbose android-device, I get errors related to Cordova not being able to find certain gradle files. Here's some output from my console:

sarah@sarah-ThinkPad-X220:~/simple-todos$ meteor run --verbose android Getting installed version for platform android in Cordova project Checking Cordova requirements for platform Android [[[[[ ~/simple-todos ]]]]]                      => Started proxy.                              => Started MongoDB.

Indeed, the files and directories it is trying to access are not there. $ANDROID_HOME/tools/template/gradle/wrapper does not have a directory gradlew

sarah@sarah-ThinkPad-X220:~/Android/Sdk/tools/templates/gradle/wrapper$ ls gradle 

Likewise, there are no files at all in my ~/simple-todos/.meteor/local/cordova-build/platforms/android/gradle/wrapper directory, so there is no gradle-wrapper.properties.

I'm also quite uncertain about the meaning of the spawn ENOENT error.

How can I fix this?

EDIT: I wanted to test that gradle worked at all on my machine, so I made an app in Android Studio and ran it on my phone-- worked fine. My Meteor project still doesn't run on Android, but I think this tells me that gradle is working (somewhere) on my computer.

EDIT: I searched for a gradlew directory on my computer and the only ones I found were in an android-studio, not in my $ANDROID_HOME(~\Android/Sdk). Not sure what to do with this info, but it seems relevant.

EDIT It occurred to me that the output of gradle -v might be useful:
