Building Android fails with build exception


#1

So I have an issue with building the Android platform for my app. I have tried removing and readding the android platform and it still won’t build.

I run in my terminal: ionic cordova build android --info --stacktrace

Output:

Do you have any unusual environment variables set? You can list them all with printenv. I’m particularly interested in whether this thread is relevant, because it presents with what looks like the same NPE.

About the only thing that leaps out at me is this PATH element: /usr/local/opt/gradle/bin (secondarily, the ant one).

I believe the Android build process typically downloads Gradle automatically and puts it somewhere magic, and it may be not be liking the version you (appear to) have manually installed. So can you try taking those two entries out of your PATH and see if that has any effect?


#7

Okay I uninstalled gradle, maven, ant. I then removed them all from my path environment. I then still get the same error.

Question should I roll back to 25.0.3 from 26.0.0 android sdk build tools?

I’m receiving this exact same build log with same Java version on Android SDK Build Tools 26.


#9

So I am able to get it to work on my Windows 7 desktop with Android Build tools v26 and Android 7.1.1 but on my Macbook Pro 10.12.x I keep running into issues with it having issues with gradlew “gradle wrapper”.


#10

@jonathant did you find a resolution for this error?


#11

No not on the Mac which I this thread is about. I was just saying I did get it working on another computer that was Windows.


#12

@jonathant I figured it out on Mac!

Solution:

  1. In your project -> navigate to: platforms -> android -> build.gradle.
  2. Open build.gradle
  3. Edit build.gradle. The file in my project originally had the dependencies -> classpath as gradle:2.1.3 and the gradleWrapper’s gradleVersion as 2.14.1. By following the link to Android Plugin for Gradle Version Compatibility mentioned in their comments, it was clear those were not the latest plugin versions.
  4. I updated the classpath to gradle:2.3.0 and the gradleVersion to 3.3 (as shown in the screenshot) and the build finally succeeded!

Hopefully this helps you, took me a day or two to figure out.


#13

I am able to build the Android platform on my Mac!

Thanks for the tip!
