Task 'wrapper' not found in root project 'android'


#43

This worded for me:

Go to the site https://gradle.org/releases, download the lastest version in some folder.
Unpack the zipfolder and create a symbolic link: sudo ln -sf /PATH-TO-BIN-FOLDER/gradle /usr/bin/gradle


#44

I couldn’t resolve it by creating a symlink. Instead, i’ve copied gradle directory to /usr/share and then i’ve added /usr/share/gradle/bin to my system PATH. Gradle binary seems not to resolve its dependecies if it isn’t run from gradle/bin directory


#45

i have tried all of your suggestions and even upgraded gradle to 4.xx and still the same issue , i even tried

ionic cordova platforms remove android
ionic cordova platform add android@6.3.0

only to get different errors

here is part of the error

                    FileUtils filePlugin = (FileUtils) pm.getPlugin("File");
                                            ^
