updated akka and akka-http versions

[touchdown]

Purpose

Update akka version from 2.5.26 to 2.5.27
Update akka-http version from 10.1.10 to 10.1.11

References

Relevant issue #2070

[touchdown]

the build failed to fetch deps that are present on maven, can we retry the build please?

[seglo]

I created #2072 to update akka-http before I saw this PR. Since you created yours first we'll go with it :)

We were having trouble with build caches. I cleared them and restarted the build.

For reference

The version of akka-http includes a fix to make transient connection error exception messages more clear. akka/akka-http@d46130d

[touchdown]

it failed on 3 separate tests, 2 of which pertains to timeouts and one on docs? docs.javadsl.SlickTest.testFlowWithPassThroughKafkaExample(SlickTest.java:272)

[seglo]

These are all transient failures related to slow processing capabilities of the travis build. The build looks good otherwise.

Transient failures

• [Failure] CsvFormattingSpec should format simple value (timeout) #2075 (new, but non-reproducible locally)
• Failed: HttpRequestsSpec should support custom endpoint configured by endpointUrl #1802
• [Failure] Slick testFlowWithPassThroughKafkaExample #2003

LGTM

I don't see compelling reasons for why Alpakka should upgrade these dependencies at this time. We should maybe be more clear on that users should control and upgrade their Akka and Akka HTTP versions independently of Alpakka. This is even more relevant during the Akka 2.5/2.6 transition.

@seglo and I discussed this more, as we are approaching Alpakka 2.0 it is actually a good time to upgrade Akka things.

LGTM.

UPDATE: Irrelevant - ignore this - turned out to be a bug in my project.

I'm unsure if this is relevant, but I upgraded my projects today as follows:

akka  2.5.23 -> 2.5.27
akkaHttp 10.1.8 -> 10.1.11
alpakka 1.1.1+30-c1934ed4 -> 1.1.2

I'm experiencing some weirdness and I'm wondering if it is due to the 1.1 branch of Alpakka being left on older versions of Akka. I did get the warning:

ManifestInfo - Detected possible incompatible versions on the classpath. Please note that a given Akka version MUST be the same across all modules of Akka that you are using, e.g. if you use [2.5.27] all other modules that are released together MUST be of the same version. Make sure you're using a compatible set of libraries. Possibly conflicting versions [2.5.27, 2.5.23] in libraries [akka-protobuf:2.5.27, akka-actor-typed:2.5.23, akka-actor:2.5.27, akka-slf4j:2.5.27, akka-stream:2.5.27, akka-stream-typed:2.5.23]

I'm now trying another release of my project with Alpakka as 2.0.0-M2 given the closer proximity of Akka releases, but if that works then that would mean that Alpakka 1.1 might need an upgrade of its Akka dependencies. I shall report back.

You need to pull up the transitive Akka dependencies (akka-actor-typed, akka-actor-typed) to the same Akka version.

Thanks. Got it.
