Groovy parser does not support multiple closure arguments without parentheses

[jevanlingen]

What's changed?

Support for multiple closure arguments without parentheses.

What's your motivation?

If you have a piece of Gradle task like:

copySpec {
    from { 'src/main/webapp' } { exclude "**/*.jpg" }
    rename '(.+)-staging(.+)', '$1$2'
}

it won't work because the Groovy parser could not parse multiple closure arguments without parentheses.

Have you considered any alternatives or workarounds?

You can workaround the problem, by adding parentheses:

copySpec {
    from({ 'src/main/webapp' }, { exclude "**/*.jpg" })
    rename '(.+)-staging(.+)', '$1$2'
}
