Unresolved reference war.getWebAppDir()

[rahulkhimasia]

In my project I apply the WAR plugin and have call war.getWebAppDir().
In Gradle 4.10.2 which has kotlin DSL 1.0-rc-6 that call works file.
But in Gradle 5.0-rc-3 which has Kotlin DSL 1.0.3 that call fails with the message Unresolved reference : getWebAppDir

Thank you for the report @rahulkhimasia.

The following works for me with Gradle 5.0-rc-3:

plugins {
    war
}

println(war.webAppDir)
println(war.getWebAppDir())
war {
    println(webAppDir)
    println(getWebAppDir())
}

Could you please provide more detail? A reproducer would be ideal.

I have distilled my relevant source code into this file MultiProjectRoot.tar.gz.

Here are the steps you need to execute to reproduce my problem.

1. tar --extract --gunzip --file MultiProjectRoot.tar.gz
2. cd MultiProjectRoot
3. gradle :WarProject1:simpleTask1

The problem is that when war.webAppDir is placed inside a tasks{ } block it does not work in 5-rc-3. But it works without any problem in 4.10.2.

Thanks @rahulkhimasia, I can reproduce now.

Gradle 5 introduced accessors for tasks, meaning in your WarProject1/build.gradle.kts script:

tasks {
    create("simpleTask") {
        println(war.webAppDir)
    }
}

war now resolves to tasks.war which is the War task, instead of resolving to project.war which is the WarPluginConvention that has this webAppDir property. The War task doesn't.

You need to disambiguate as follow:

tasks {
    create("simpleTask") {
        println(project.war.webAppDir)
    }
}

This can be discovered by either navigating to the source of webAppDir from your IDE, or printing war to get to know what it is.

This is expected and part of Gradle 5.0 changes, closing.

Thank you for your explanation Paul. That makes sense. I was able to fix the issue and I have been able to migrate and validate all my other build.gradle.kts scripts from 4.10.2 to 5.0-rc-3. Looking forward to the final 5.0 release.
