How do I define a variable for the dependency version in Gradle

Question

I am currently trying to migrate a Maven project to Gradle

In my Maven version I have the dependency versions all listed out l

Answer 1

the version-value-variable works only in double quotes.

Below implementation doesn't work with single quotes.

ext {
   springBootVersion = '2.2.7.RELEASE'
}
dependencies {
   implementation 'org.springframework.boot:spring-boot-starter-web:$springBootVersion'
}

Below one works with double quotes:->

ext {
    springBootVersion = '2.2.7.RELEASE'
}
dependencies {
    implementation "org.springframework.boot:spring-boot-starter-web:$springBootVersion"
}

So, now I have to convert all single quotes to double quotes. Can someone help me to make version-value-variable work with single quotes?
