Error: Class path contains multiple SLF4J bindings - scala

While this does seem to be a common issue, I have looked and tried many fixes for sbt and this dependency issue without success.
Setup is a simple query to hive from scala using the run command within IntelliJ. The command is using JDBC to connect to hive.
val sql = s"select * from ${tableName} where user_id = '1'";
val res = stmt.executeQuery(sql);
Here are my Imports:
import java.sql.{SQLException, Connection, DriverManager, ResultSet, Statement}
import scala.collection.mutable.ArrayBuffer
//import scala.io.{BufferedSource, Source}
import scala.language.postfixOps
//import scala.util.matching.Regex
//import java.sql.ResultSetMetaData
The sbt file is as follows:
ThisBuild / version := "0.1.0-SNAPSHOT"
ThisBuild / scalaVersion := "2.13.8"
lazy val scriptClasspath = Seq("*")
lazy val root = (project in file("."))
.settings(
name := "RevProject_1",
libraryDependencies += "org.apache.hive" % "hive-jdbc" % "3.1.2",
)
Now for the errors as displayed in IntelliJ Terminal:

I have tried the following:
Excluding the dependency in sbt using:
libraryDependencies += "group" % "artifactId/name" % "version" exclude("group", "artifactId/name")
libraryDependencies += "org.apache.logging.log4j" % "log4j-slf4j-impl" % "2.10.0" exclude("org.apache.logging.log4j", "log4j-slf4j-impl")
I am not sure if there are any errors in the previous code. If so let me know.
I have attempted to locate a POM.xml and an IVY file in my project. Unfortunately I have been unable to locate them. I have read through many of the answers for this issue within this site and run into the scenario where it is not applicable due to using Scala/sbt or lack of direction for someone of my skill level to learn how to properly implement the fix.
to further view the project files you can see them at:

Any assistance with resolving this issue is greatly appreciated.

Liquibase stopped working after moving from 3.6.3 to 3.8.7 or 3.10.2

I was using liquibase 3.6.3 and everything worked fine but today I've moved to 3.10.2 and suddenly I can't run any database updates. The only thing which is in the log file I've pasted below.
We run on DB2 for IBM i.
We use power shell scripts and bat scripts and if we run them outside of the liquibase, everything works fine but when those scripts get called from liquibase after the upgrade, it hangs on the last line from below log.
liquibase.log exist.
Liquibase found.

Unable to start Drill in distributed mode

I am trying to setup drillv1.18 running. Facing the error below.
The drill-override.conf points to the zookeeper which runs on port 12181. On starting in distributed mode, it fails with the following log output. But the embedded mode has no issues.
It appears like permission issue, but both zookeeper, drill, zookeeper data-dir all are running under the same user.

Version 1.17 has no issues in starting in distributed mode.
The issue here is with the zookeeper version. Perhaps you use 3.4.X version, but the current version of Drill requires 3.5.X. As a workaround, you may replace zookeeper jar in jars/ext/zookeeper-3.5.7.jar and jars/ext/zookeeper-jute-3.5.7.jar with the jars that corresponds to your zookeeper version.
In Addition to the answer of Vova Vysotskyi, you may find more information in Drill documentation about this issue:
https://drill.apache.org/docs/distributed-mode-prerequisites/
Starting in Drill 1.18 the bundled ZooKeeper libraries are upgraded to version 3.5.7, preventing connections to older (< 3.5) ZooKeeper clusters. In order to connect to a ZooKeeper < 3.5 cluster, replace the ZooKeeper library JARs in ${DRILL_HOME}/jars/ext with zookeeper-3.4.x.jar then restart the cluster.

UnresolvedAdressException milo

Im trying to connect from an basic Milo-Client (ReadSample), but getting UnresolvedAdressException. Both Client and Server are in an remote Network and I only got Access to the Client. I'm pretty sure its not a Firewall since I can Connect with other Clients (Prosys OPC UA Client) and i can see that the ip is resolved to an Host-Name in the Logs:
Server is opc.tcp://192.168.115.40:49580 aka opc.tcp://Extern-Mess-Rec:49580 (tried both in UaTcpStackClient.getEndpoints(url).get();)

The server you're getting endpoints from is probably returning "Extern-Mess-Rec" as its hostname, which you can't resolve.
See this answer for how to deal with that scenario.

GraphML inport into Titan

I'm new in Titan world. I would like to import data stored in GraphML file into a database.
I downloaded titan-1.0.0-hadoop1
I run ./titan.sh
I run ./gremlin.sh
In Gremlin console I wrote:
:remote connect tinkerpop.server ../conf/remote.yaml
Next, I wrote:
graph.io(IoCore.graphml()).readGraph("/tmp/file.graphml")
I got message:
No such property: graph for class: groovysh_evaluate
Could you help me?
IMO the most interesting logs from gremlin-server.log:

You need to create a graph. the graph keyword isn't declared anywhere in your script.
This is briefly covered in the Titan Server documentation, but it is easily overlooked.
The :> is the "submit" command which sends the Gremlin on that line to the currently active remote.
In step 5, you need to submit your script command to the remote server. In the Gremlin Console, you do this by starting your command with :submit or :> for shorthand.
:> graph.io(IoCore.graphml()).readGraph("/tmp/file.graphml")
If you don't submit the script to the remote server, the Gremlin Console will attempt to process the script within the console's JVM. graph is not defined locally, and that is why you saw the error in step 6.
Update: Based on your gremlin-server.log it looks like the issue is that the user that starts Titan with ./bin/titan.sh start doesn't have the appropriate file permissions to create the directory (db/berkeley) used by the default graph configuration (titan-berkeleyje-server.properties). Try updating the file permissions on the $TITAN_HOME directory.

Error after generating model

I wanted to lern xtext, for many years i lerned xpand and xtend and worked fine, but xtext seems to replaced the other both. And the xtext way looks fine to me.
As start i read follwing Tutorials: http://www.eclipse.org/Xtext/documentation/101_five_minutes.html, Including "15 Minutes Tutorial" and "15 Minutes Tutorial - Extended" and others. So i created a simple "Model"
grammar org.bs.test.Test with org.eclipse.xtext.common.Terminals
generate Test "http://www.bs.org/test/Test"
Test:
main=TMain;
TMain:
'main' name=ID
'done';
Generated on following way: "GenerateTest.mwe2" > right click > 'Run As' → 'MWE2 Workflow'.
Then made a copy of the Project. It was already my second or third try to find out what i made wrong.
Now i changed in the model following line: "main=TMain;" to "main=TMain?;". Then i used 'MWE2 Workflow' again, which run successful, but after running following happens:
Everthing files under 'src-gen/org/bs/test/Test/' and files in the subfolders 'impl' and 'util' are deleted. So they get deleted, then i copied the saved project and try following action on "Test.xtext" > right click > 'Run As' → 'Generate Xtext Artifacts', which result in the same.
There are two question for me:
1) What is the difference between "Generate Xtext Artifacts" and "MWE2 Workflow" and when did i do need them. I cannot figure that out on the Tutorial and especialy when to use them.
2) What did i wrong, and what i have to do to create generate the elements from the changed model
I could not find much on this, i hope someone could help me. I did not find something to both question.
EDIT 1:
When i create a complete new test project it works:
project name: org.test
name: org.test.MyTest
extensions: mytest
with following xtext:
grammar org.test.MyTest with org.eclipse.xtext.common.Terminals
generate myTest "http://www.test.org/MyTest"
Test:
main=TMain;
TMain:
'main' name=ID
'done'
But when i do the same with following input:
Project name: org.bs.craass
Name: org.bs.craass.CraAss
Extension: craass
xtext:
grammar org.bs.craass.CraAss with org.eclipse.xtext.common.Terminals
generate craAss "http://www.bs.org/craass/CraAss"
CraAss:
main=CAMain;
CAMain:
'main' name=ID
'done';
Later i will try following: install a new eclispe emf and create a new workspace.
EDIT2:
So i tested a new workspace, there it look liks, that it is working. Perhaps something with the old workspace. Like in a comment, in the orginal workspace, after i get a good "version", i wanted to put it on git (learning reason). Since then this not working anymore. Here some output of the generation:

The trouble seems, that i have following:
grammar org.bs.craass.CraAss with org.eclipse.xtext.common.Terminals
but on the other side:
terminal INTEGER : '-'?('0'..'9')+;
terminal VAR_TERMINAL : '_' ('a'..'z'|'A'..'Z'|'_'|'0'..'9')*;
terminal REGISTER_TERMINAL : ('ax' | 'bx' );
terminal FUNCTION_TERMINAL : (('a'..'z'|'_'|'0'..'9')*'.')?('a'..'z'|'A'..'Z'|'_'|'0'..'9')*;
And in the org.eclipse.xtext.common.Terminals is
terminal INT returns ecore::EInt: ('0'..'9')+;
But i have no what to do with it.
The Problem itself, while generating everthing in srce-gen/, except the generated java files under src-gen/org.bs.craass.craAss and subfolder. Now there are created, too. So more i try to find out, so less the error was reproducable. Well, i will see, when i push it to git again, perhaps the error comes back.
So far thanks
running the workflow directly or calling generate language artefacts does the very same. the workflow reads your Xtext file and generates all infrastructure Xtext provides for your language. thus you have to call it if you change your grammar or the workflow itself. if you have a misconfiguration on your language or a broken grammar the generation may fail. also the workflow may refer to project names which may have to be adopted as well (dont know how you do the copy and paste - you should use the Xtext Project wizard to create the project to be safe)
