Gradle - auto update dependency version - gradle

Question

I have Jenkins CI pipeline which releases applications. This process works in a way that person triggers release job for application. This job checks all project dependencies via gradle dependencies command. For all dependencies that are snapshot release jobs are triggered automatically.
Release job simply upgrade lib/application version and deploys it in artifactory.
How can I automaticaly upgrade SNAPSHOT dependency version to release version in gradle?
My build.gradle file looks like this:
Properties versions = new Properties()
versions.load(new FileInputStream(rootProject.projectDir.path + "/version.properties"))
dependencies {
compile("projectA:${versions.projectAVersion}")
compile("projectB:${versions.projectBVersion}")
}
and version.properties file
projectAVersion=1.1.0-SNAPSHOT
projectBVersion=1.1.0-SNAPSHOT
In fact I am looking something similar to maven versions plugin.
Is it possible to automatically upgrade version numer inside build.gradle? How?
And harder version - is it to possible to upgrade version number when version is in external version.properties file?
EDIT
In fact I just need Maven versions-plugin (versions:use-releases and versions:use-next-releases) functionality in Gradle.

I am not that clear with your question. What I understood is that, you need to dynamically update the version value after each build.
What you can do is, get the properties value. Remove -SNAPSHOT. Update 1.1.0 with increment after each build. Like 1.1.1, 1.1.2 etc.
This can be done by
task testing {
Properties props = new Properties()
//getting and loading the property file
//Give proper path to file
File propsFile = new File('version.properties')
props.load(propsFile.newDataInputStream())
//Now strip of -SNAPSHOT and get the last digit and increment it by 1
Integer rand = props.getProperty('lastDigit').toInteger()+1
String variable=rand.toString()
//Append -SNAPSHOT with 'variable and set the property
props.setProperty('version',variable)
props.store(propsFile.newWriter(), null)
}
This will work, if my understading of your problem is correct.
