Gradle project build with dhall as dependency hangs

[jneira]

Hi, i've reproduced the error in windows 10 simple adding compile eta('dhall-1.15.1') in the build.gradle of the simple example of the plugin

The build.gradle is:

plugins {
    id 'com.typelead.eta' version '0.7.5'
    id 'application'
}

eta {
    version = '0.8.0b2'
    etlasVersion = '1.4.0.0'
}

sourceSets {
  main {
    eta {
      srcDir 'eta'
    }
  }
  test {
    eta {
      srcDir 'eta-test'
    }
  }
}

dependencies {
  compile eta('base:4.8.2.0')
  compile eta('dhall:1.15.1')
}

compileEta {
  options {
    args = ['-Wall']
    extensions {
      CPP
    }
    cpp = ['-DHELLO=1']
  }
}

The build hangs in Building aeson-1.2.3.0 (lib)... step
Moreover, when i kill the gradle building with ctrl-c, the etlas, eta and java proccesses spawned continue running.

I've checked that an etlas installatation with the version fixed (eta version = '0.8.0b2' selected by etlas after cleaning, etlasVersion = '1.4.0.0' downloaded from site) terminates correctly

• If i replace the eta block with this one:

eta {
  useSystemEta = true
  useSystemEtlas = true
}

• I get another error:

PS C:\Users\Javier\dev\lang\eta\dhall\dhall-eta> gradle build

> Task :setupEnvironmentEta UP-TO-DATE
WARNING: You have not explicitly set the version of Eta to be used, so the version available on your system, 0.8.0b3, will be used.

This is not recommended since it will make this build non-reproducible. Please supply a value for the 'version' property in an eta { .. } block.

* What went wrong:
Execution failed for task ':compileEta'.

eta is in this directory!

I recently reproduced the hanging of Building aeson-1.2.3.0 (lib)... on OS X when building with Gradle. Will need to take a look at this.
