I'm using org.apache.commons:commons-configuration2 to load and merge configuration from different sources:
val root = CompositeConfiguration()
root.addConfiguration(SystemConfiguration())
val configurations = Configurations()
root.addConfiguration(configurations.properties("defaults.properties"))
My problem is that whenever I run this code I get an exception:
Exception in thread "main" java.lang.NoClassDefFoundError:

It says that org.apache.commons.beanutils.BeanIntrospector is not found. If I add commons-beanutils:commons-beanutils:1.9.3 to the classpath the problem is solved but the main problem is that I'm using Apache Spark 2.3.0 in a managed environment (Databricks) and it comes with commons-beanutils:1.7.0 so I can't do anything about the beanutils version.
How can I solve this problem?
You may want to try using commons-configuration:commons-configuration:1.10 if you only want the composite configuration feature form commons-configuration. It works like this:
val root = CompositeConfiguration()
root.addConfiguration(SystemConfiguration())
root.addConfiguration(PropertiesConfiguration("defaults.properties"))
Configurations 2 won't work with 1.7.0 bean utils according to their documentation.

I am currently trying to set up an existing JAVA project in IntelliJ IDEA.
The project just won't run past the below posted code snippet on my machine.
try {
this.wb = new XSSFWorkbook (inputStream);
out.print_c("42");
}
I already updated all my dependencies (my Setup is posted at the end of the post), checked the Excel file for any kind of protection (it has none), but I still get the following error messages:

I hope anyone has an idea what could be the problem here.
Thank you in advance.

In my program I have several modules placed in different folders and all of them are dependent on a "core" module.
I have already setup a configuration for Intellij to run the program, but every time I try to run I receive a ClassNotFound Excpetion. I'm not sure if this is due to my core module having a similar packages i.e. com.adpetlabs.flappybird
Could the problem be related to the packages or something else? I really need help in resolving this

NoClassDefFoundError means Java couldn't find the Class it was looking for. That normally means:
You defined wrongly the classpath.
Java is finding and using the wrong version of the jar (probably because of Maven dependency hell).
Solution for 1 is to check the classpath: make sure you are including the jar that defines org.apache.spark.sql.SchemaRDD.
Solution for 2 is to check if you have a Maven dependency that depends (transitively) on an older version of the resource that defines that class.
for those who've managed to use this java implementation of leveldb https://github.com/dain/leveldb/
I'm getting the following stacktrace when I try to execute the code in the readme:
NoClassDefFoundError occurs when runing the following line:
DB db = factory.open(new File("example"), options);

I confirmed that new File("example") returns a non-null value; same as the variable options
I import two jars built from the source into my library:
1.leveldb-api.jar
2.leveldb.jar
I've tried this with releases 0.6, 0.7 and 0.8-SNAPSHOT and always get the same error.
Could it be something I'm doing wrong ...or missing?
com.google.common.collect.util from guava is a dependency of the leveldb library but for some reason adding it explicitly as a dependency for my java project solved the problem.
When I try to simulate my little project, I decided to use jme3 library and browsed the jar file through Configure-> JDK Profiles-> Add Archieve-> JME3-core.jar and ran the project sample code. The code was written in a website and I got the exception as:

Process completed.
Is the problem about the native libraries kind of issue which is also need to be dealt with J3D libraries? I mean, do I need to follow some instructions about installing and importing JME3 libraries? If so, can anyone tell me the instructions or where to download the correct .jar file?
find a similar discussion here ..this might be relevant ...
