Non-resolvable parent POM for io.sarl.tycho-parent

Hi there,

When compiling my basic SARL project against SARL 0.5.6, I am running into the following error:

[ERROR] Failed to execute goal io.sarl.maven:sarl-maven-plugin:0.5.6:compile (default-compile) on project elsim-prolog: Unable to get dependency information for io.sarl.maven:io.sarl.maven.sdk:jar:0.5.6: Failed to process POM for io.sarl.maven:io.sarl.maven.sdk:jar:0.5.6: Non-resolvable parent POM for io.sarl:io.sarl.tycho-parent:[unknown-version]: Could not transfer artifact io.sarl:io.sarl:pom:0.5.6 from/to org.eclipse.ide.neon (http://download.eclipse.org/releases/neon/): Cannot access http://download.eclipse.org/releases/neon/ with type p2 using the available connector factories: BasicRepositoryConnectorFactory
[ERROR]   io.sarl.maven:io.sarl.maven.sdk:jar:0.5.6

This occurs when building from CLI with mvn install and not within SARL Eclipse 0.5.6. I have tried removing old versions of 0.5.6 from my .m2 and retrying, however this has not helped. For reference, my POM file is as follows:

Hopefully this helps, Matt

Release 0.5.7 of SARL will be available soon on the Maven Central server and on the SARL website, after all the servers will be synchronized.

Please re-open this issue if it does not solve your problem.
