Convert project from Android Studio version 2 to 3- problem with configuration

I have problem with configuration of android project. I upgraded Android Studio [AS] from v2 to v3 and got many problems. I changed gradle as is in documentation:
gradle-wrapper, gradle plugin version, repositories google or jcenter instead of maven. Please look at configuration:
I have project called mytwayapp which have build.gradle:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.0'
//{ url "http://jcenter.bintray.com/" }
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
dependencies {
implementation project(':app')
}
Next I have module called app with build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion '27.0.3'
// buildToolsVersion "26.0.2"
defaultConfig {
applicationId "com.mytway.activity.registerformactivity"
minSdkVersion 21
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
dexOptions {
preDexLibraries = false;
javaMaxHeapSize "2g"
}
sourceSets { main { assets.srcDirs = ['src/main/assets', 'src/main/res/assets/fonts'] } }
testOptions {
unitTests.returnDefaultValues = true
}
lintOptions {
abortOnError false
}
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.google.android.gms:play-services:8.4.0'
implementation 'com.android.support:appcompat-v7:23.1.1'
implementation 'com.android.support:support-v4:23.1.1'
implementation 'com.android.support:support-v13:23.1.1'
implementation 'joda-time:joda-time:2.9.4'
implementation files('../libs/MPAndroidChart-v3.0.1.jar')
//to remove when Dex is over memory
testImplementation group: 'org.powermock', name: 'powermock-api-easymock', version: '1.6.6'
testImplementation 'org.powermock:powermock-mockito-release-full:1.5.4'
testImplementation 'org.powermock:powermock-api-mockito:1.6.6'

testImplementation 'org.easymock:easymock:3.1'
// testCompile files('build/lib/powermock-easymock-1.6.6-full.jar')
testImplementation 'junit:junit:4.12'
}
Next is gradle-wrapper:

Problem:
I cannot sync with gradle,If I try then error:

When I try install from cmd, then:
./gradlew install -x test

BUILD FAILED in 2s
It means that problem is with main build.gradle with dependencies to ":app" but it looks good.
I tried refreshed, rebuild, invalidate, restarted and still have a problem.
Project structure looks strange here is a screen:
ANSWER:
Tips from below are not worked, I downgrade Android Studio from 3.4 to 3.1 and after some cosmetics change it compile. Thanks for your time.

Try to update to latest versions:
dependencies {
classpath 'com.android.tools.build:gradle:x.x.x'
}
And buildToolsVersion in build.gradle

Try change de compileSDkVersion and targetSdkVersion with the same number prefix of buildToolsVersion in app gradle file, like this:
android {
compileSdkVersion 27
buildToolsVersion '27.0.3'
// buildToolsVersion "26.0.2"
defaultConfig {
applicationId "com.mytway.activity.registerformactivity"
minSdkVersion 21
targetSdkVersion 27
versionCode 1
versionName "1.0"
}

cannot install two flavors of an app with Android Annotations

I have an app using Android Annotations and everything is working fine except one thing - you cannot install both flavors on the same device despite the fact that they have different applicationId.
Researching this I came across some problems (that other people had) with annotation processing and flavors, and as I recall this was an issue also here, but we've manage to add following snippet and everything worked.
apt {
arguments {
androidManifestFile variant.outputs[0]?.processResources?.manifestFile
resourcePackageName android.defaultConfig.applicationId
}
}
Until the other day we've didn't notice, that we couldn't install two flavors at once on one device. I've tried changing the gradle but every time I've ended up with the same problem or breaking the gradle script.
As I've mentioned, I've tried all things that I could think of and the online search didn't turn up anything useful, so if anybody have any idea I'll appreciate it.
Following there are my build.gradle scripts.

Thanks in advance for any suggestion. Kudos!

OK, so thanks to #ligi pointing me to the right track.
We have a similar project with a very similar setup and the main difference are the Android Annotation used in one of them, an that has mislead me.
The bottom line is that I've had a provider in the manifest that I wasn't aware of, and the authority conflict did occur at that point.
Thanks for your time. Kudos.

Error: Cause: Peer not authenticated -- Gradle build of android project

I researched similar questions but none of the answers solved my problem. When I try to build the starter code for a coding assignment I get the following error:

I didn't manage any of those files as I don't have gradle experience yet.
Could you help me to figure out what went wrong?
Thank you very much.
P.S.:
The log files give me this error:

I am working on one library project in android. I want to upload my library to the JCenter. I have created bintray account etc & followed all steps which are mentioned here http://inthecheesefactory.com/blog/how-to-upload-library-to-jcenter-maven-central-as-dependency/en

When I am doing this gradlew install then I am getting this error
FAILURE: Build failed with an exception.
* What went wrong:
Task 'install' is ambiguous in root project 'TestApp'. Candidates are: 'installDebug', 'installDebugAndroidTest'.

I spent three days on same but could not get proper solution of it. Please suggest how to resolve it.

Perhaps you forgot to add these lines to the end of your Library Module build.gradle:
apply from: 'https://raw.githubusercontent.com/nuuneoi/JCenter/master/installv1.gradle'
apply from: 'https://raw.githubusercontent.com/nuuneoi/JCenter/master/bintrayv1.gradle'

You are telling gradle to do the 'install' task but it is telling you that there is no 'install' task and gives suggestions of close task matches like 'installDebug'.
Basically your plugins do not include an install task. If you want to see all the tasks that are available to you run the command below
gradlew tasks --all

}
apply from: 'maven_push.gradle'

The HoloColorPicker library has gradle tasks for uploading to the Maven repository that require some properties to be set for the gradle environment (usually in gradle.properties).
The easiest solution would be to remove the line from build.gradle:
apply from: 'maven_push.gradle'

I have not try the solution given by myanimal, but i have try out another thing which works with all the project which have similar issue during importing it. myanimal's solution is related to only one project, and for every project you should have to follow same thing.
But with my solution you might have to do it only once for all future projects.
For my solution do like below:
- create a file ~/.gradle/gradle.properties with the following contents:
nexusUsername=
nexusPassword=
Hope this will help you more for all projects.
