Some plugins, e.g., cobertura-maven-plugin, use ${plugin.artifacts}
to setup classpath of externally launched jvms and they expect slf4j
to be available among plugin dependencies. At the same time slf4j
is already part of maven core runtime and it needs to be filtered
out from plugin and build extension realms to avoid duplicate classes
on classpath.
The fix is to move core artifact filtering from plugin dependency
resolver to class realm manager. This way ${plugin.artifacts} still
includes all compile/runtime scoped plugin dependencies but runtime
classpath only has plugin unique artifacts.

read ${maven.projectBasedir}/.mvn/extensions.xml and create core
extensions realms during maven runtime bootstrap. this required
short-lived bootstrap plexus container to resolve extensions.
individual extensions realms are wired to maven.ext realm according
to META-INF/maven/extension.xml exported packages specification

javax.inject.* and org.slf4j.* packages were already exported, but
corresponding artifacts were not. this resulted in same classes
present in multiple classlaoders and caused hard-to-troubleshoot
build failures in some cases.

I will try and collect all deprecated code at the bottom of classes with Munge markers and
use this in conjunction with a definitive list of classes to be purged in order to use
one code line to safely experiment with Maven 4.x.
Push MavenExecutionRequestPopulator down to only operate in the MavenCli. Two of the three methods were already called from MavenCli so now all of them are. In the process I deleted a bunch of code and pursue my quest to remove Settings from the core in order to make a general configuration mechanism that can be plugged into the core via the MavenCli.
Also removed the requirement of the LegacyRepositorySystem in the DefaultMavenExecutionRequestPopulator which breaks another tie with the legacy code. I took the bits that were needed and a lot of the code, after tracing through it, is redundant so it has been deleted.
Turning off:
injectMirror( request, request.getRemoteRepositories(), request.getMirrors() );
injectMirror( request, request.getPluginArtifactRepositories(), request.getMirrors() );
in DefaultMavenExecutionRequestPopulator
Results :
Failed tests:

There is mirror evaluation code in DefaultMaven:newRepositorySession( MavenExecutionRequest request ) which appears to
duplicate this logic but not quite enough for the ITs to pass.

Turning off:
injectProxy( request.getRemoteRepositories(), request.getProxies() );
injectProxy( request.getPluginArtifactRepositories(), request.getProxies() );
in
DefaultMavenExecutionRequestPopulator
Result:
The ITs pass
So the code is not needed so it has been deleted.

Turning off:
injectProxy( request.getRemoteRepositories(), request.getProxies() );
injectProxy( request.getPluginArtifactRepositories(), request.getProxies() );
injectAuthentication( request.getRemoteRepositories(), request.getServers() );
injectAuthentication( request.getPluginArtifactRepositories(), request.getServers() );
in
DefaultMavenExecutionRequestPopulator
Result:
The ITs pass
The code in DefaultMaven:newRepositorySession( MavenExecutionRequest request ) appears to populate proxies and authentication correctly. The injectAuthentication code has been deleted.

This is also perfunctory in DefaultMavenExecutionRequestPopulator after tracing through it:
request.setRemoteRepositories( getEffectiveRepositories( request, request.getRemoteRepositories() ) );
request.setPluginArtifactRepositories( getEffectiveRepositories( request, request.getPluginArtifactRepositories() ) );
MavenExecutionRequest has been extended with toolchains, which is filled by MavenCli
Interfaces have been extended with new methods, assuming only Maven provides implementations
Consolidated plugin realm setup logic in DefaultMavenPluginManager.
Extensions realm is fully setup during project loading and the same
realm is used to both load extensions and execute plugin goals now.

DefaultJavaToolChain was the only way to access JDK toolchain
javaHome parameter and was used by some clients, notably Tycho.
The class is now marked as deprecated and clients are adviced to
use JavaToolchainImpl instead.

this hides use of deprecated/legacy ArtifactFactory and allows custom

MojoExecution scope was only available for maven plugins and could not
be used for components defined in maven core or maven code extensions.
Session scope was only available for maven core and core extensions
but did not work for components from maven plugins.
Made both custom scopes available available in all realms.

Fixed JDK8 IT failure for MavenITmng3004ReactorFailureBehaviorMultithreadedTest#testitFailFastSingleThread
It turns out the execution order of the modules in the build can be incorrect, in some cases severely incorrect.
For parallel builds this can have all sorts of interesting side effects such as classpath
appearing to be intermittently incorrect, missing jars/resources and similar.
The -am options and -amd options may simply fail with the incorrect build order
because expected dependencies have not been built and actual dependencies may not have been built.
The underlying problem was that ProjectDependencyGraph#getDownstreamProjects and getUpstreamProjects
did not actually obey the reactor build order as defined by ProjectDependencyGraph#getSortedProjects,
even though the javadoc claims they should.
This has only worked by accident on earlier JDK's and might not have worked at all (basically
depends on Set iteration order being equal to insertion order). JDK8 has slightly different
iteration order, which caused the IT failure.
This problem may be the root cause of MNG-4996 and any other issue where the modules build
in incorrect order.
The bug affects:
parallel builds
command line -am (--also-make) option
command line -amd (also-make-dependents) option
On all java versions, although visibility might be somewhat different on different jdks.
Added simple unit test that catches the problem.
The cuplrit was the resetRepositories method in tandem with the repository
list instances being shared between ModelResolvers.
- The copy constructor for the ModelResolvers now creates new lists.
- The resetRepositories method has been removed. Instead there is a
'replace' parameter on the addRepository method that allows the
desired parameter replacement of MNG-5639 to take place.
