I have written a Copy task with ant’s ReplaceTokens filter used.
snippet of build.gradle
ext {
appVersion=“1.0”
baseDir=file("/app/foo")
srcDir="$baseDir/src"
buildDir="$baseDir/build" } task complexCopy(type: Copy){
from “$srcDir”{
include(“build.xml”)
}
into “$buildDir”
filter(
ReplaceTokens, tokens: [“app.version”: “$appVersion”, “user”:“admin”]
) }
And I am getting following errors - Could not copy ‘…/src/build.xml’ to ‘…/build/build.xml’
stack trace -
Exception is: org.gradle.api.tasks.TaskExecutionException: Execution failed for task ‘:complexCopy’.

BUILD FAILED
I had found one work around as follows - tokens: [“app.version”: “$appVersion”.toString(), “user”:“admin”.toString()]
But I guess there should be something else rather than toString().
Any ideas?
