Multi example doesn't build

[sir4ur0n]

I tried to run the multi example but I get several errors.

The first time:

However if I run the same command again, it seems to go further, but breaks:

Hi, i've reproduced the first error but it works in the second try. Do you tried the plugin before? Maybe the gradle cache could contain bad versions of libraries. Sometimes wiping out the ~/.gradle directory makes it work again.

The log of my test (to compare with yours):

PS C:\Users\Javier\dev\lang\eta\gradle-eta\examples\multi> gradle run

Welcome to Gradle 4.7!

Here are the highlights of this release:
 - Incremental annotation processing
 - JDK 10 support
 - Grouped non-interactive console logs
 - Failed tests are re-run first for quicker feedback

For more details see https://docs.gradle.org/4.7/release-notes.html

I just tried on another computer (Windows this time), I still can't build it.

First error is exactly the same. Second (and next tries) all result in the same error:

Jumm, so you did the test in a fresh computer with no previous tries to build the example, right? What version of the plugin are you trying? the master version? I'll try using the gradle wrapping instead a system install (i am using an external gradle 4.7) to try reproduce the error.

[sir4ur0n]

Yes, that was on a fresh clone of this repo, never tried to install it before. I was on master branch. I was using gradlew which is supposed to make the build fully reproducible 😄

[jneira]

Hi, sorry for the delat but i get to reproduce the error, wiping out my local ~\eta\0.8.0b2 and ~\etlas\0.8.0b2. We have to investigate why but the versions used in master eta-gradle don't work anymore (and it should!) In the meanwhile i've tried newer versions of etlas, eta and libs and they have worked for me:

• multi/build.gradle

  
  plugins {
  id 'com.typelead.eta' version '0.7.9'
  id 'application'
  }

allprojects { repositories { mavenCentral() } }

eta { version = '0.8.6b2' etlasVersion = '1.5.0.0' }

dependencies { compile eta('text:1.2.3.0') compile eta('memory:0.14.14') compile project(':hio') compile project(':java-shallow') }

- `multi/hio/build.gradle`
```groovy
plugins {
    id 'com.typelead.eta'
}

dependencies {
    compile eta('text:1.2.3.0')
    compile eta('bytestring:0.10.8.2')
    compile project(':java-deep')
}

hope it helps!

[sir4ur0n]

Your fix seems to work 😄 Waiting for the PR to be merged before closing.

Closing since the relevant PR was merged.
