[undertow-dev] Building Undertow

[Brad Wood]

I'm trying to build Undertow using the (sparse) instructions here and
having a heck of a time.

https://undertow.io/undertow-docs/undertow-docs-2.1.0/index.html

cd undertow && mvn install

So firstly, I'm not super familiar with Maven (not a full time java dev)
but when I skip the tests, the build fails.  Here is the note in the docs,
which is confusing for a couple reasons:

If you attempt to build with -Dmaven.test.skip=true for your initial build
> the build will fail, as the core test jar will not be built and the Servlet
> module has a test scoped dependency on this jar. Either use -DskipTests,
> or just let the tests run the first time.
>

   - First it says the build will fail if the tests are skipped, but then
   seems to imply that I can work around this by setting some system
   properties.
   - What is the difference between the *maven.test.skip* property and the
   *skiptests* property?  Do I need both of them?

If I try to run the build like so (Using Maven 3.6.3 and java 11) using a
fresh clone of the Undertow repo with the "master" branch checked out:

mvn install -Dmaven.test.skip=true -DskipTests


I get this build failure still:

[ERROR] Failed to execute goal on project undertow-servlet: Could not
> resolve dependencies for project
> io.undertow:undertow-servlet:jar:2.1.4.Final-SN
> APSHOT: Could not find artifact
> io.undertow:undertow-core:jar:tests:2.1.4.Final-SNAPSHOT -> [Help 1]
>

So, I'm not sure what to do there.  The docs state that setting those JVM
args is an alternative to running the tests but it doesn't work.

Now, the first thing I tried was actually just to let the tests run, but
this proved to be even more troublesome than skipping the tests!  I get
tons of test failures and other errors and the behavior differs whether I'm
using Java 8 or Java 11 (fun!) and the tests usually just hang and won't
complete.

When I run the build (with tests) on Java 1.8.0_161 they hang on this test
and never finish.

[INFO] Running io.undertow.server.handlers.ReceiverTestCase


When I run the build (with tests) on Java 11.0.6, I get the following
errors:

[ERROR]
> testSpnegoSuccess(io.undertow.server.security.SpnegoDigestAuthenticationTestCase)
>  Time elapsed: 0.01 s  <<< FAILURE!
> java.lang.AssertionError: Expected header not found.
>
> [ERROR]
> testSpnegoSuccess(io.undertow.server.security.SpnegoBasicAuthenticationTestCase)
>  Time elapsed: 0 s  <<< FAILURE!
> java.lang.AssertionError: Expected header not found.
>
> [ERROR]
> testSpnegoSuccess(io.undertow.server.security.SpnegoAuthenticationTestCase)
>  Time elapsed: 0 s  <<< FAILURE!
> java.lang.AssertionError: expected:<401> but was:<403>
>
> [ERROR]

>  Time elapsed: 0.042 s  <<< FAILURE!

> [ERROR]
> testRegexPattern(io.undertow.server.handlers.SameSiteCookieHandlerTestCase)
>  Time elapsed: 0.027 s  <<< ERROR!
> javax.net.ssl.SSLException: Connection reset
>

And then it hangs on the same test case that Java 8 hangs on
(io.undertow.server.handlers.ReceiverTestCase)

What does it take to get a local build of Undertow working?  If it matters,
I'm trying to build on a Windows 7 machine.

Thanks!
