Hello,
i just started trying packaging with ionic pro.

But the first build failed:

FAILURE: Build failed with an exception.

  • Where:
    Build file ‘/usr/src/app/platforms/android/build.gradle’ line: 20

  • What went wrong:
    A problem occurred evaluating root project ‘android’.

Local android building works fine.

What is your ionic info output?

#info info

cli packages: (C:\Users\nowrap\AppData\Roaming\npm\node_modules)

@ionic/cli-utils  : 1.18.0
ionic (Ionic CLI) : 3.18.0

global packages:

I would try to add the Android platform locally and see if that fixes it.

If not, this looks a bit like something the Ionic people should look at via their support channels as there is not much to go on:

hmmm, platforms are installed:

cordova platform ls
Installed platforms:
android 6.4.0
browser 5.0.1
ios 4.5.3

local android builds are working:
ionic cordova run android -l -c

6

Hmm, then I would try to find out why ionic info isn’t listing them… suspicious. (But can very well be unrelated to the original problem)

i removed them and readded them.
now they are listed:

local packages:

@ionic/app-scripts : 3.1.2
Cordova Platforms  : android 6.3.0 ios 4.5.3
Ionic Framework    : ionic-angular 3.9.2

ionic pro can build the ios package

the android package still fails. but now the error is different:

Checking the license for package Android SDK Platform 26 in /opt/android-sdk/licenses
Warning: License for package Android SDK Platform 26 not accepted.

FAILURE: Build failed with an exception.

  • What went wrong:
    A problem occurred configuring root project ‘android’.

You have not accepted the license agreements of the following SDK components:
[Android SDK Platform 26].
Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager.
Alternatively, to learn how to transfer the license agreements from one workstation to another, go to Exporting licenses - Android Studio Project Site

Next I would do:
https://cordova.apache.org/announcements/2017/11/09/android-release.html

9

done, build is running:

ionic cordova platform rm android
ionic cordova platform add android@6.4.0

// edit
build failed again with the initial posted error

10

So although you are on the current cordova-android now you are getting the Gradle error again? Then I would say again that this is something support should look at: http://ionicframework.com/support#support

That worked for me. I had upgraded Gradle from Android Dev environment and had the build issue.
removing the android platform manually, then re-adding fixed it.
