Daniel Sun updated GROOVY-8138:
-------------------------------
Fix Version/s: 2.6.0-alpha-3
> Compile static to support streams
> ---------------------------------
>
> Key: GROOVY-8138
> URL: https://issues.apache.org/jira/browse/GROOVY-8138
> Project: Groovy
> Issue Type: New Feature
> Components: Static compilation
> Affects Versions: 2.4.10
> Environment: Windows 7, JDK 1.8.0_66
> Reporter: Iurii
> Assignee: Daniel Sun
> Priority: Major
> Fix For: 2.6.0-alpha-3, 3.0.0-alpha-2, 2.5.0-rc-2
>
>
> The following code
> {code}
> import groovy.transform.CompileStatic
> import static java.util.stream.Collectors.toList
> @CompileStatic
> class Test {
> static void main(String[] args) {
> List<String> tables = ['a', 'b']
> println tables.stream().filter { tableName -> tableName.contains('a') }.collect(toList())
> }
> }
> {code}
> fails with the error:
> Error:(9, 55) Groovyc: [Static type checking] - Cannot find matching method java.lang.Object#contains(java.lang.String). Please check if the declared type is right and if the method exists.
> But works fine with compile dynamic.
> It would be great if CompileStatic get all required types from the steam (type info should be there, Java can handle similar code)
