Difficulties with using multiple bindings file in different locations - and instructions how to do it - maybe worth adding to doco

[boardbloke]

Hiyah,

Thanks for this plugin - its proved very useful in my project. I did however have a problem using it with bindings files which I thought worth raising as it might be worthwhile adding to the doco

The problem I encountered was using it from the Groovy DSL. I have multiple WSDL each with their own binding file - I was trying to use the following config which was failing:

wsdl2java {
    cxfVersion = "${project.ext.cxfVersion}" // Referring to this via project.ext to avoid name clash
    markGenerated = "yes-jdk9"
    wsdlDir = file("$projectDir/src/main/resources/wsdl")
    addCompilationDependencies = true

    //  Map wsdls and cxf-parameters
    includesWithOptions = [
            "wsdl1.wsdl" : ['-b', 'binding1.ejb'],
            "wsdl2.wsdl" : ['-b', 'binding2.ejb'],
            "wsdl3.wsdl" : ['-b', 'binding3.ejb']
    ]
}

Doing the above - with the wsdl and bindings file in the same directory ("$projectDir/src/main/resources/wsdl") I was getting an error

I eventually found that the whole path to the binding file needs to specified - i.e.

wsdl2java {
    cxfVersion = "${project.ext.cxfVersion}" // Referring to this via project.ext to avoid name clash
    markGenerated = "yes-jdk9"
    wsdlDir = file("$projectDir/src/main/resources/wsdl")
    addCompilationDependencies = true

    //  Map wsdls and cxf-parameters
    includesWithOptions = [
            "wsdl1.wsdl" : ['-b', "$projectDir/src/main/resources/wsdl/binding1.ejb".toString()],
            "wsdl2.wsdl" : ['-b', "$projectDir/src/main/resources/wsdl/binding2.ejb".toString()],
            "wsdl3.wsdl" : ['-b', "$projectDir/src/main/resources/wsdl/binding3.ejb".toString()]
    ]
}

Note that it was not enough to just quote the path to the binding file relative to the project directory - e.g. 'src/main/resources/wsdl/binding1.ejb', so in Groovy I used a Groovy string "$projectDir/src/main/resources/wsdl/binding1.ejb".

Note also that the toString() is required because the Array needs to be a List of String and its not being converted automatically - without the toString() you get:
