java.lang.ClassNotFoundException: aleph.http.core.HeaderMap with 0.4.5-alpha6

[rborer]

Hi,

I'm currently integrating aleph 0.4.5-alpha6 in one of my projects. As soon as I add a require on aleph.http.client-middleware namespace I receive the following ClassNotFoundException when compiling my project:

java.lang.ClassNotFoundException: aleph.http.core.HeaderMap, compiling:(aleph/http/client_middleware.clj:734:1)

I'm using Clojure 1.9.0 with java version "1.8.0_161".

[kachayev]

@rborer I assume we're talking about running the code in REPL, right?

[gsnewmark]

It probably was broken in this commit 😞 🙈 a782c36#diff-0699d0c8d41a57446aff9b64094ddf35L15

Type hint requires class to be available on classpath, but I believe it's generated dynamically on namespace load.

[rborer]

@kachayev I have this issue when I run lein compile :all actually.

[rborer]

@kachayev Eratta: If I run lein compile :all twice in a row, it works. But with lein do clean, compile :all it fails.

[kachayev]

@rborer Right, because it generates class first, then uses it.

[kachayev]

@rborer Will try to find a solution for this. Thanks for reporting!

[rborer]

@kachayev Thanks.

I tried to look at it and I'm also struggling to build master branch, it exhibit a similar behaviour which may require changes in https://github.com/ztellman/byte-streams:

Again, a second pass with lein compile :all and it's fine :-)

[kachayev]

@rborer That's the same problem with initialization flow that requires the class to be compiled prior to using it for any type hints.

[kachayev]

kachayev@b0cc7ac this one should fix the problem with HeaderMap type hint. Still looking into the problem with byte-streams (the reason for that is not the same, unfortunately).

[kachayev]

Okay, let's do the following

#388

The problem with byte_streams.graph.Type is definitely not that simple to tackle, and (thanks @gsnewmark for the help), - it hasn't been working for a long time already. So, I'll try to tackle that separately.

[rborer]

Thanks.

Looks like byte-streams problem has already been reported under clj-commons/byte-streams#34 .
