[jira] [Updated] (MRESOLVER-413) BF collector causes failure when -Dmaven.artifact.threads=1 used

     [ https://issues.apache.org/jira/browse/MRESOLVER-413?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tamas Cservenak updated MRESOLVER-413:
--------------------------------------
    Description: 
When Maven invoked with {{-Dmaven.artifact.threads=1}} the BF collector fails:
{noformat}
[ERROR] Invalid poolSize: 1. Must be greater than 1.
java.lang.IllegalArgumentException: Invalid poolSize: 1. Must be greater than 1.
    at org.eclipse.aether.util.concurrency.ExecutorUtils.threadPool (ExecutorUtils.java:46)
    at org.eclipse.aether.internal.impl.collect.bf.BfDependencyCollector$ParallelDescriptorResolver.<init> (BfDependencyCollector.java:488)
    at org.eclipse.aether.internal.impl.collect.bf.BfDependencyCollector.doCollectDependencies (BfDependencyCollector.java:156)
    at org.eclipse.aether.internal.impl.collect.DependencyCollectorDelegate.collectDependencies (DependencyCollectorDelegate.java:222)
    at org.eclipse.aether.internal.impl.collect.DefaultDependencyCollector.collectDependencies (DefaultDependencyCollector.java:87)
    at org.eclipse.aether.internal.impl.DefaultRepositorySystem.collectDependencies (DefaultRepositorySystem.java:305)
    at org.apache.maven.project.DefaultProjectDependenciesResolver.resolve (DefaultProjectDependenciesResolver.java:157)
{noformat}

This is wrong, as according to https://maven.apache.org/resolver/configuration.html means "Number of threads to use for collecting POMs and version ranges in BF collector." and the configuration should accept 1 as well.
Or reconsider to NOT observe this configuration for BF thread pool, as the configuration may be set via two (new and old) keys: {{aether.dependencyCollector.bf.threads}} or {{maven.artifact.threads}}. Latter is probably wrong choice.
