Project Kickstarter homepage will be changed. Please replace the links in the README and in the doc index page to the location of the zipped files. https://developer.lightbend.com/guides/akka-quickstart-scala/

Change this:

"Download and unzip the example:

Download the zip file from Lightbend Tech Hub(https://developer.lightbend.com/start/?group=akka&project=akka-quickstart-scala) by clicking CREATE A PROJECT FOR ME.
Extract the zip file to a convenient location:"

To this:

"Download and extract the zip file(https://example.lightbend.com/v1/download/akka-quickstart-scala?name=akka-quickstart-scala) to a convenient location:"

Because our scala files are being run through the g8 templating engine now (to set the package name correctly), using $ signs in the code is now problematic.

While the $ signs can be escaped as \$, paradox does not pick up on this.

Should we find a way to post-process the snippet in paradox?

For akka versions stop using the "stable" as that'll point to 2.6

Change any doc links from current -> 2.5

Documentation with issue

Akka Quickstart Scala docs:
https://developer.lightbend.com/guides/akka-quickstart-scala/define-actors.html

Expected Behavior

The documentation should largely correspond to the example code, e.g. "Akka Quick Start" actors or Greeter actors, especially where specific object names from the code are concerned.

Actual Behavior

The documentation contains references to Hello, "Hello World", HelloWorld etc, which seem to be from a prior incarnation of a quick start Hello World example. (References to the example as being "Hello World"-like are probably natural enough, it's more the specific object names in the documentation that should be in synch with the example.)

I am intending to read / work through these docs myself, so would be happy to fork and make some proposed updates in the process, if that'd be welcome.

I just downloaded the latest version of this template and I am getting this error when trying to compile the akka quickstart:

The current readme shows

sbt -Dsbt.version=0.13.17 new akka/akka-quickstart-scala.g8

and the build.properties, has;

sbt.version=1.1.6

These two versions are not the same and a lagging behind the latest release, 1.3.6

Can't get this working. Breaks with the following error.

Exiting due to error in the template
File: /var/....../src/main/g8/build.sbt, context [anonymous] 9:14 internal error:
org.stringtemplate.v4.compiler.STException: context [anonymous] 9:14 attribute name isn't defined

Reported by Ruth in akka/akka#23149

In the section that describes how to run Hello World, it says:
To run Hello World:

In a console, change directories to the top level of the unzipped project.

For example, if you extracted the project to your root directory, from the root directory, enter: cd akka-scala-seed

The default name is now akka-quickstart-scala, so the previous text should be changed to:

For example, if you used the default project name, akka-quickstart-scala, and extracted the project to your root directory, from the root directory, enter: cd akka-quickstart-scala

I assume the same is true for the Java example but I haven't tested it yet.

Per build.sbt:
scalaVersion := "2.13.1"
akkaVersion = "2.6.10"

This was run on Xubuntu 18.04 with OpenJDK 11.0.8.

To get a quickstart zip, I followed the directions at the Lightbend Tech Hub

When I tried to run sbt, there was an error message that at least Java 1.6+ was required. Somehow 11.0.8 was seen as less than 1.6 . I commented out the version check and everything ran fine.

Perhaps this is actually an issue with sbt, but the end result is that without poking around in sbt-dist/bin/sbt-launch-lib.bash, I wouldn't have been able to run the quickstart example.

Not a big deal but...

The Intellij screenshot at https://developer.lightbend.com/guides/akka-quickstart-scala/intellij-idea.html (source at https://github.com/akka/akka-quickstart-scala.g8/blob/2.6.x/docs/src/main/paradox/intellij-idea.md) shows the "SBT project" as ~/Downloads/hello-akka-scala. That should probably be ~/Downloads/akka-quickstart-scala now.

I am currently working on a backend component (still WIP) based on this template that I would like to release under the MIT license. However, I have had trouble finding information whether this is possible. In other words: can I release a project under the MIT license even if it is a derived work from a template released under the CC0?

I tried to find some information related to this, but did not find anything conclusive. Below are some comments/links I found.

• It seems CC0 is not approved by the OSI. They also recommend At this time, we do not recommend releasing software using the the CC0 public domain dedication.
• I probably do not understand all the issues related to this correctly (and IANAL). However, the MIT license specifically grant the right to sublicense the code. However, part 3 (Public License Fallback) in the CC0 text mentions that the fallback license is "non sublicensable". However, according to gnu.org, the CC0 (and the Public License Fallback) are compatible with the GNU GPL. Related discussion.

When running the template you are asked for an organisational name / package path.
E.g. com.example.

if you change this to something else, the "package" declarations are updated as expected.
However the imports in the test are not;

I,.e. if change the package to "com.bob"

The test looks like this;

package com.bob

import akka.actor.testkit.typed.scaladsl.ScalaTestWithActorTestKit
import com.example.Greeter.Greet
import com.example.Greeter.Greeted
import org.scalatest.WordSpecLike

import com.example.Greeter.Greet
import com.example.Greeter.Greeted

have both NOT been updated to reflect the changed package.
