Hi Robert,
well it is already handled in the POM only for JDK 7:

...
    <profile>
      <id>jdk7</id>
      <activation>
        <jdk>(,1.7]</jdk>
      </activation>
      <build>
        <plugins>
          <plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-invoker-plugin</artifactId>
            <configuration>
              <properties combine.children="merge">
<https.protocols>${https.protocols}</https.protocols>
<arguments>-Dhttps.protocols=${https.protocols}</arguments>
              </properties>
            </configuration>
          </plugin>
        </plugins>
      </build>
    </profile>
...

Of course, this only takes care of when you release something with the plugin using JDK 7.  When building maven-release itself you will have to provide the system property for JDK 7, but not when using UK mirror ;-)

Cheers, Clemens

Hi Clemens,

We need to stay as close as possible to the real world.
With JDK8+ it should work without its being set, so the preferred way it to execute it without the value being set. And this way, once we must move TLS 1.3 we don't have to change all our tests. Here's how we do it with our Jenkins script[1], only  activate it for Java 7.

Hi Robert,
if TLSv1.2 is needed, then why not put it explicitly into the pom in line 266 [0] instead of using ${https.protocols}?

Hi Clemens,

please see https://central.sonatype.org/articles/2018/May/04/discontinued-support-for-tlsv11-and-below/ We'll need to contact Sonatype and verify if they included http://uk.maven.org/maven2/  as well (they should...)

However, AFAIK nowadays there's no need anymore to explicitly refer to uk, it is already handled by Central CDN

thanks,
Robert

Hi Robert,
thanks for the insight.  Shouldn't it fail with JDK 7 Update 80 even
with this parameter since the backport for TLSv1.2 came with Update 95 [0]?
Since when does this requirement exist?  Just checked it:  I'm using UK
mirror [1].  This works without TLSv1.2. Maybe thats why i didn't
noticed before.
But we had problem at work contacting the Atlassian Repo from our Nexus
that ran with JDK 7 Update 80.  In that case we switched back to JDK 6
Update 211.

Cheers, Clemens

The plugin is indeed still Java 7 compatible, but that means you must
execute it with -Dhttps.protocols=TLSv1.2 when building it with JDK 7,
otherwise it'll fail because this is a requirement when downloading
from Central.
Our CI server scripts already add this argument when running with Java
7, on your local machine it must be done by hand. This is not
restricted to the integration tests. Try to remove your local repo and
start any project running with Maven and Java 7, it'll fail very fast,
i.e. by the first plugin.

thanks,
Robert

Hello everyone,

I have provided a PR for MRELEASE-229 [1] and added some JUnit tests
recently.

Now I was wondering if i should provide an IT, too, and had a look
into it:

Running

mvn verify -Prun-its

with Maven 3.6.1 and JDK 7 Update 80 fails:

...

[INFO] Building: projects\perform\MRELEASE-459\pom.xml
[INFO] run post-build script verify.groovy
[INFO]   The post-build script did not succeed. assert matcher.find()
         |       |
         |       false
         java.util.regex.Matcher[pattern=\Q[DEBUG] Additional
arguments: \E(?:-Dhttps.protocols=TLSv1.2
)?-P(.+)\Q-DperformRelease=true -f pom.xml\E region=0,154745 lastmatch=]
[INFO]           projects\perform\MRELEASE-459\pom.xml ............
FAILED (10.4 s)

...

IMHO it has something to do with TLSv1.2 not being backported to JDK
7 Update 80.  But i may be wrong.

With JDK 8 Update 212 the tests run successfully.

My question is:  Should the IT still run with JDK 7?  I thought so
since maven-release can still be build with it.  If some versions of
JDKs are not capable of being used for IT, shouldn't the IT run fail
fast (by enforcing the eligible versions)?

That was one question I have now redarding the ITs of maven-release.
I post my other questions in separate mails.

Regards,

Clemens
