是否有与Scala的文字标识符等效的Groovy？

Question

Scala's literal identifiers are described in Need clarification on Scala literal identifiers (backticks) .

Background: I'm converting an Ant build system to Gradle. We currently have a file dependencies.properties with definitions like:

com.netflix.archaius.archaius-core.rev=latest.release

But Groovy doesn't like the . and - in the property names (since they're operators). Rather than changing the names of the properties and everything using them, is there a way to tell Groovy to consider the . and - as simply another character in the property name?

Answer 1

The following does not provide literal identifiers, as in Scala, but it should solve your root problem. Given this dependencies.properties file:

foo=bar
com.netflix.archaius.archaius-core.rev=latest.release

and then this Gradle script:

ant.property(file: "dependencies.properties")

task go() {
    println ant."com.netflix.archaius.archaius-core.rev"
    println ant.foo
    println "done."
}

the output is (edited for brevity):

bash-3.2$ gradle go
latest.release
bar
done.
