Is resource filtering in Gradle possible without using tokens?

Question

The recommended way to do resource filtering in Gradle is by having tokens in the properties file and then replacing them when processing.

Example

#          


        

Answer 1

Can use thing like placeholder if you want.

In config.properties file

var1=${var1}
var2=${var2}

In gradle.properties file

processResources {
    filesMatching('**config.properties') {
        expand(
            'var1': project.property('var1'),
            'var2': project.property('var2'),
        )
    }
}

Answer 2

The spring-boot approach

project.version=X.X.X.X
info.build.version=@project.version@

Answer 3

You could use the following (not tested):

processResources {
    filesMatching('**/config.properties') {
        filter {
            it.replace('localhost', project.property('myhost'))
        }
    }
}

Or you could have a default file, used during development in your IDE, and have another file containing tokens and replacing the development one when building using gradle. Something like this (not tested)

processResources {
    exclude '**/config.properties'
    filesMatching('**/config-prod.properties') {
        setName 'config.properties'
        filter ReplaceTokens, tokens: [
            "myhost": project.property('myhost')
        ]
    }
}
