Error while loading package in Intellij after adding Maven dependencies (Scala) - java

I'm using intelij ultimate trial. I'm new to programming and a friend recommended I learn functional programming before object oriented programming. Searching the web I decided to learn Scala. The problem is I can't even set up IDE environment. I copied the dependencies but I'm unsure what they do. I'm just following along a coursera course right now. I don't know what the issue is. I don't know if I provided enough information. I used an online IDE when I was learning python
Currently using:
SDK 2.13.4
JDK 1.8
I've tried:
changing JDK to 11.0, 11.03, 13.0, and 15.0. I also changed SDK 2.11, 2.12.9,2.13.5 witch each JDK

How to add com.google.zxing API to my java project in VSCode?

I'm working on an application, and I need zxing API for generating QR Codes, so I tried adding it to my Project in VS Code however, as soon as I tried importing it into a class, it throws an error com.google.zxing is not accessible.

But I still have problem:

NoClassDefFoundError: org/apache/spark/sql/DataFrame in spark-cassandra-connector

Everything seems fine but when I run test cases then It stuck between the process and log some error message saying:

Thank you in advance!!
Can anyone please help me with this ?
If you need more info please let me know!!

Try to add dependency
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-sql_2.10</artifactId>
<version>${spark.version}</version>
<scope>provided</scope>
</dependency>
Also make sure that your version spark-cassandra-connector is compatible with version of Spark you're using. I had the same error message even with all proper dependencies when was trying to use older spark-cassandra-connector with newer Spark version. Refer to this table: https://github.com/datastax/spark-cassandra-connector#version-compatibility

Could not initialize com.ibm.mq.MQEnvironment

I've upgraded my maven dependencies for IBM MQ from these(version: 6.0.2.5):
<dependency>
<groupId>com.ibm</groupId>
<artifactId>mq</artifactId>
<version>${ibm-mq-version}</version>
</dependency>
<dependency>
<groupId>com.ibm</groupId>
<artifactId>mqjms</artifactId>
<version>${ibm-mq-version}</version>
</dependency>
<dependency>
<groupId>com.ibm.disthub2</groupId>
<artifactId>dhbcore</artifactId>
<version>DH610-Gold</version>
</dependency>
<dependency>
<groupId>com.ibm</groupId>
<artifactId>mqetclient</artifactId>
<version>${ibm-mq-version}</version>
</dependency>
To that(version: 7.5.0.5):
<dependency>
<groupId>com.ibm</groupId>
<artifactId>mq-jms-all</artifactId>
<version>${ibm-mq-version}</version>
</dependency>
Now, everytime I try to run my project, I get the following error:
nested exception is java.lang.NoClassDefFoundError: Could not initialize class com.ibm.mq.MQEnvironment
The maven-dependency is imported correctly and is also visible in Eclipse in the maven-dependencies-tab. Also i see the com.ibm.mq.jar in the classpath.
I've googled a lot and the only real solution, which worked for some people was, to add the connector.jar. But I'm already using the jar:
<dependency>
<groupId>javax.resource</groupId>
<artifactId>connector</artifactId>
<version>${connector-version}</version>
</dependency>
Am I missing something?

IBM MQ from these(version: 6.0.2.5):
To that(version: 7.5.0.5):
IBM moved the MQException to the 'com.ibm.mq.jmqi.jar' file.
As per the the MQ Knowledge Center, you need the following jar files for MQ JMS programming:
com.ibm.mq.commonservices.jar
com.ibm.mq.headers.jar
com.ibm.mq.pcf.jar
com.ibm.mq.jmqi.jar
connector.jar
jms.jar
dhbcore.jar
rmm.jar
jndi.jar
ldap.jar
fscontext.jar
providerutil.jar
CL3Export.jar
CL3Nonexport.jar

Exactly the same problem and this fixed it
<dependency>
<groupId>javax.resource</groupId>
<artifactId>connector</artifactId>
<version>${connector-version}</version>
</dependency>
These are my dependencies.
<dependency>
<groupId>com.ibm.mq</groupId>
<artifactId>com.ibm.mq.commonservices</artifactId>
<version>7.0.1.4</version>
</dependency>
<dependency>

</dependency>
<dependency>
<groupId>com.ibm</groupId>
<artifactId>com.ibm.mqetclient</artifactId>
<version>7.0.1</version>
</dependency>

For Eclipse (Dynamic Web Project (Servlet)) you need copy files:
com.ibm.mq.commomservices.jar
com.ibm.mq.defaultconfig.jar
com.ibm.mq.headers.jar
com.ibm.mq.jar
com.ibm.mq.jmqi.jar
com.ibm.mq.jms.Nojndi.jar
com.ibm.mq.pcf.jar
com.ibm.mqetclient.jar
com.ibm.mqjms.jar
connector.jar
dhbcode.jar
fscontext.jar
jms.jar
to /WebContext/WEB-INF/lib, then add them into Project (Project -> Properties -> Java Build Path -> Add External JARs).
After all, go through these steps:
close project
close Eclipse
open Eclipse
open project.
Good Luck!

Drools hello world maven dependencies

I'm trying to run very simple application using Drools and for a couple of hours now can't set up pom.xml with all dependencies.
Here is how it looks now:
<dependencies>
<!-- Drools engine -->
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-core</artifactId>
<version>5.4.0.Final</version>
</dependency>
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-compiler</artifactId>
<version>5.4.0.Final</version>
</dependency>
<!-- Test -->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.7</version>
<scope>test</scope>
</dependency>
</dependencies>
Just like in
https://community.jboss.org/wiki/DroolsMaven
But what I get:
org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java:org.drools.rule.builder.dialect.java.JavaDialectConfiguration'

Caused by: java.lang.RuntimeException: The Janino jar is not in the classpath
If I try to add Janino I get another exception about some missing classes(I don't think I should add Janino here anyway as it should be a dependency of something else).
Do I miss anything in my pom?
Thanks!
Leonty

By default, drools-compiler uses the eclipse compiler (JavaDialectConfiguration.ECLIPSE) for the java dialect which is a transitive dependency:
<dependency>
<groupId>org.eclipse.jdt.core.compiler</groupId>
<artifactId>ecj</artifactId>
</dependency>
However, if you prefer the janino compiler(JavaDialectConfiguration.JANINO), you need to add the janino dependency yourself because it is an optional transitive dependency:
<dependency>
<groupId>org.codehaus.janino</groupId>
<artifactId>janino</artifactId>
<optional>true</optional>
</dependency>
Look at the droolsjbpm-parent pom to find out which version to use.

Turned out just the right version of Janino is needed for Drools 5.4.0 Final: 2.5.16
Newer versions luck class used in Drools.
