How do I resolve this ProductFlavours error - android-studio

Question

This is the first time I've used Android Studio and I can't build this app.
Can anyone tell me how to fix this code?
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
buildToolsVersion "28.0.3"
defaultConfig {
applicationId "org.settingsdeployer"
minSdkVersion 15
targetSdkVersion 21
versionCode 4
versionName "1.2"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
normal {
applicationId "org.settingsdeployer"
versionCode 4
versionName "1.2"
}
french {
applicationId "org.settingsdeployer"
versionCode 5
versionName "1.2_fr"
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
}
I'm getting these errors when it tries to sync:

I made the requested changes and it sync'd but now I can't make an apk:
That's great, it sync'd the build without errors but now when I try to generate an apk i get more errors. I have no idea what I'm doing!
UPDATE:
After adding flavorDimensions it sync'd the build without errors but now when I try to generate an apk i get more errors. I have no idea what I'm doing!. Here is the error log:

I'm getting these errors when it tries to sync: ERROR: All flavors
must now belong to a named flavor dimension. Learn more at
https://d.android.com/r/tools/flavorDimensions-missing-error-message.html
Affected Modules: org.settingsdeployer
The flavor dimension problem is happened because you haven't add the flavorDimensions to your build.gradle. There must be at least one flavorDimensions. Something like this:
android {
...
defaultConfig {...}
buildTypes {
debug{...}
release{...}
}
// you need to specifies one flavor dimension.
flavorDimensions "version"
productFlavors {
normal {
// This property is optional if you are using only one dimension.
dimension "version"
applicationId "org.settingsdeployer"
versionCode 4
versionName "1.2"
}
french {
dimension "version"
applicationId "org.settingsdeployer"
versionCode 5
versionName "1.2_fr"
}
}
}

This warning is telling that we need to use either api or implementation to replace the compilation when adding dependencies. So, change the dependencies block to something like this;
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:21.0.3'
}
