gradle - Groovy generated constructor missing during compile -

i have setup in call generated constructor(@tupleconstructor) of groovy class(product) java class(productservice). ide shows generated constructors , compilation used work. now, unknown reasons, compilation fails because compiler doesnt find parameterized constructors anymore:

productservice.java:31: error: constructor product in class product cannot  applied given types;  required: no arguments   found: string,boolean,boolean,float  reason: actual , formal argument lists differ in length 

and current gradle(2.4) setup:

apply plugin: 'groovy' apply plugin: 'java'  project.sourcecompatibility = 1.8 project.targetcompatibility = 1.8  sourcesets.main.java.srcdirs = [] sourcesets.main.groovy.srcdir 'src/main/java' ... dependencies {     compile 'org.codehaus.groovy:groovy-all:2.4.+'     testcompile 'org.spockframework:spock-core:1.0-groovy-2.4' } 

groovy class:

@tupleconstructor class product {     string name     boolean bool1     boolean bool2     float price } 

constructor call in java class(fails compile):

... products.add(new product("parliament", true, false, 10.50f)); ... 

analysis:

this looks me joint compilation issue. transform @tupleconstructor runs after groovy did create .java stub files, causing java compilation part fail. have worked before, because compiled groovy part independent , reused existing class files (no clean). sadly limitation of stub generator , there not way fix issue in groovy, if transform supposed stay in same phase.

solutions:

• use groovy-eclipse batch compiler
• don't use transforms run after stub generator
• create multi module build in gradle, compile groovy part independent
