I currently started using broadleaf commerce framework. I downloaded the demo site from their site which includes 4 folders (site, admin, api, core). then I successfully ran the mvn install command. when I wanted to run mvn spring-boot:run the following error occured:

2018-05-27 13:59:26.784 INFO 13536 --- [ main] utoConfigurationReportLoggingInitializer :

I carefully read this error and spent lots of hours and finally I found that this is related to solar search engine. I decided to run solar locally. I downloaded solar search engine and configured it according to the instructions given in this link but unfortunately I did not find solrconfig.xml and schema.xml in the version that I downloaded, so I searched on net and found other files. I re-ran the admin area but I got the follosing error:

I have no idea what to do next. I would be glad if you help me solve the issue.

I had a similar issue that gave the same error. Upon inspecting the log file (/tmp/solr-/solr-/server/logs/solr.log on my linux box) I found that it couldn't start the jvm. When I downgraded to open-jdk-1.8 installed via yum (I had manually installed open-jdk-11 before), solr was able to start properly.

So I'd make sure you're using a supported java version and that it is installed in a way that solr expects.
