Tasks not listed on eclipse

I’ve written these tasks:

task createQAWar(type: War, dependsOn: classes) {
    ...
}

task createDevelopmentWar(type: War, dependsOn: classes) {
    ...
}

task createProductionWar(type: War, dependsOn: classes) {
    ...
}

task createDists(dependsOn: [createQAWar, createDevelopmentWar, createProductionWar])

I’ve imported project using BuildShip eclipse plugin. As you can see, they are not listed on available tasks:

Why do these tasks are not detected?

If you didn’t specify the group attribute for your tasks then they are hidden by default. Just open the Gradle tasks view menu and enable the Show All Tasks option.
