To whom it may concern:
I had (at least) two issues
1) setting CoreDescriptor property/ies
Properties coreProps = new Properties();
coreProps.setProperty( CoreDescriptor.CORE_CONFIGSET, "configset" );
CoreDescriptor cd = new CoreDescriptor( container, "test", pathToSolrCores +
"/test", coreProps );
2) solr.xml
<str name="configSetBaseDir">${configSetBaseDir:c:/tmp/solr/configsets}</str>

My unittest looks alike:
String pathToSolr = "C:/tmp/solr/";
String pathToSolrCores = pathToSolr + "cores"; File solrCoresDir = new File(
pathToSolrCores ); if ( solrCoresDir.exists() ) {
FileUtil.deleteDirectory( solrCoresDir ); } FileUtil.createDirectories(
pathToSolrCores ); CoreContainer container = CoreContainer.createAndLoad(
pathToSolrCores, new File( pathToSolr + "solr.xml" ) ); // String
coreRootDirectory = container.getCoreRootDirectory(); Collection<String>
coreNames = container.getAllCoreNames(); Assert.assertTrue( coreNames.isEmpty()
); CoreDescriptor cd = new CoreDescriptor( container, "test", pathToSolrCores +
"/test" ); cd.getSubstitutableProperties().setProperty( cd.CORE_CONFIGSET,
"configset" ); // I also tried cd.getSubstitutableProperties().setProperty(
cd.CORE_CONFIGSET, pathToSolr + "configsets/configset" ); // SolrCore core =
container.create( cd ); coreNames = container.getAllCoreNames();
Assert.assertFalse( coreNames.isEmpty() );
The structure of /tmp/solr looks like this:
C:\TMP\SOLR
├───configsets
│ └───configset
│ └───conf
| └───schema.xml
| └───solrconfig.xml
└───cores
└───solr.xml
solr.xml:
<solr>
<shareSchema>true</shareSchema>
<configSetBaseDir>c:/tmp/solr/configsets</configSetBaseDir>
<solrcloud>
...
</solrcloud>
<shardHandlerFactory name="shardHandlerFactory"
...
</shardHandlerFactory>
</solr>

I haven't done this myself, but it is defined as a constant in the
CoreDescriptor:
http://www.solr-start.com/javadoc/solr-lucene/org/apache/solr/core/CoreDescriptor.html#CORE_CONFIGSET
You could also look at the tests and see whether it is used.

Alex.
