Dynamic, Typesafe query syntax invalid in VSCode and Eclipse (works in IntelliJ)

Let me start by saying I'm learning Java, and come from the .NET/C# world.
TL;DR:
This syntax does not work in VSCode or Eclipse IDE, does in IntelliJ. Why? What am I missing?
import path.to.class.Foo;
import path.to.class.Foo_; // cannot be resolved error
...
Foo_.barID; // cannot resolve to a variable
The underscore_ notation just causes the above errors... ugh
Long version:
I work on an API, and my team is newer to the project. None of us JAVA specific devs, and we've learned a ton over the last several months. The original devs created the project using IntelliJ, and supported it using that IDE. Unfortunately, our IntelliJ licenses keep being allowed to expire and it takes a week to get it back, and I'm not good with down time, so I tried Eclipse and VSCode. When trying to debug, the project won't build because some imports are unable to be resolved, as well as some variables that appear to be using JPA 2.0 notation for Dynamic, typesafe queries.
Reading the following, this notation appears to have been around a long time, and Eclipse a long time Java IDE, so I think I'm clearly missing something.
What does an underscore concatenated to a class name mean?

https://developer.ibm.com/articles/j-typesafejpa/
I have a hard time believing this is only possible in IntelliJ, so it has to be something I'm missing within the IDE's. A package, or setting, or something that is not allowing the IDE to utilize the Criteria API?

EDIT: No longer monitoring this question since using the Community Edition of IntelliJ IDEA will work for my needs and I do not have to switch IDE's. I think the proposed answer will work for some, if not most; however, since I was unable (and unwilling to continue) to make the build work with another IDE I am leaving it unselected as the solution.

Those are so-called metamodel classes for your entities, and they are generated by Hibernate (since you have the hibernate-jpamodelgen annotation processor configured in the pom). So whenever a maven build is run, those classes are generated to a specific directory, and then Maven includes that directory with as a source location during the compile step.
Since Eclipse (and VSCode, I presume) aren't aware of this folder of generated files as a source location for the project, it doesn't recognize the generated classes. There are a couple of ways to deal with it:
You can configure the annotation processor in Eclipse so that it does the same thing as the Maven plugin. It's pretty straightfoward, but requires a one-time manual setup. A decent set of instructions is found here; the official JBoss Hibernate instructions are pretty dated, but might still be valid, found here (there's also a decent explanation of Hibernate's metamodel generation on that page, for reference).
You can rely on Maven to run the generator and just add the output folder as a source location to your Eclipse project. The default output location for APT-generated files in Maven is "target/generated-sources/apt", so you can add that to the Eclipse project's Build Path as a source folder. You can do that in the project's Properties, Java Build Path section; or just right-click on the folder and select Build Path > Use as Source Folder
.
Note that with option 2, when you change your entities you'll have to re-run the maven build (at least generate-sources phase) to see the updated generated classes.

Use the Community Edition of IntelliJ as offered by #joopeggen.
Proposed answer by #e-riz is a likely secondary answer.

How to remove or exclude transitive Log4j during maven build?

during my build (using the maven command mvn clean install) my maven compiler automatically downloads the log4j dependency 1.2.12 (repository/log4j/log4j/) but since this has vulnerability issues I need to exclude this transitive dependency download.
This is my POM (however not really needed since an empty pom would download it as well using the default mvn compiler I guess?)

You already gave half of the answer yourself: you need to change the version of the maven-compiler-plugin. Instructions can be found at https://maven.apache.org/plugins/maven-compiler-plugin/usage.html
It is always a best practice to lock versions of plugins in your pom, just to ensure you can rebuild your project in X years too.

I tried updating the compiler version but now it’s giving same transitive dependency error in maven-dependency-plug-in.
Currently it’s is using 2.8 .I tried changing it to 3.3.0 which is latest but still same issue.

java.lang.NoSuchMethodError Exception with Java reflection in a flink process

I'm trying to extend business logic of a flink process using google Reflection Library. I'm stuck with this exception at runtime.
Does somebody experimented the same issue. I suspect maven conflict but I have no idea. I pasted the exception and the pom file.

<!-- Execute "mvn clean package -Pbuild-jar" to build a jar file out of
this project! How to use the Flink Quickstart pom: a) Adding new dependencies:
You can add dependencies to the list below. Please check if the maven-shade-plugin
below is filtering out your dependency and remove the exclude from there.
b) Build a jar for running on the cluster: There are two options for creating
a jar from this project b.1) "mvn clean package" -> this will create a fat
jar which contains all dependencies necessary for running the jar created
by this pom in a cluster. The "maven-shade-plugin" excludes everything that
is provided on a running Flink cluster. b.2) "mvn clean package -Pbuild-jar"
-> This will also create a fat-jar, but with much nicer dependency exclusion
handling. This approach is preferred and leads to much cleaner jar files. -->

I'm pretty sure this is non Flink related issue. The problematic method SetsView#iterator invoked by reflections 0.9.11 comes from Guava 20.0, which you are excluding in your pom, while cassandra-driver-extras pulls in Guava 19 (which doesn't have this method). You can check that by executing:
mvn dependency:tree
You have to fix this conflict somehow between cassandra and reflections dependencies. You could try to force guava version to 20.0, drop the cassandra-driver-extras dependency or find cassandra-driver-extras version without guava dependency (Flink is shading it's Guava dependency so Flink's users do not have to deal with this problem).

Invalid or corrupt jarfile using maven

I have a project which works perfectly on eclipse, but when I try to run it on terminal using jar file then I get an error. Basically, the aim is to create a fat jar with all dependencies included.

Error: Invalid or corrupt jarfile target/NLPAnnotationController-jar-with-dependencies.jar

As suggested in a comment, double-check to see if the JAR file is really corrupt using jar tv <filename.jar>.
There are a couple of common causes for corrupt JAR files:
The file was corrupted by copying / transferring it the wrong way; e.g. using FTP in ASCII rather than BINARY mode.
The file system filled up while you were writing the file.
This is the ZIP64 problem. The original ZIP file format did not support more than 4GB in size. This was addressed by an extension to the format, but versions of Java prior to Java 7 did not support that.
Reference: https://blogs.oracle.com/xuemingshen/entry/zip64_support_for_4g_zipfile
There is a hard limit of 65535 entries in a ZIP file. Unfortunately, some Maven plugins does not entirely understand this limit. When you attempt to generate a JAR with too many entries, the result is a corrupt JAR file.
References:
Invalid or corrupt JAR File built by Maven shade plugin
Create a large zip assembly with maven-assembly-plugin
The first three explanations are unlikely in your case, for various reasons. That leaves a Maven plugin problem. One of the Q&As that I found said that this was fixed in version 2.5 of the maven-assembly-plugin. But you appear to be using a later version. So maybe this is not the problem after all.
Anyhow:
Check that you are using a Java 7 or later JRE or JDK on your build and execution platforms.
Try updating the version of the maven assembly plugin in your POM to the latest available.

maven assembly: unresolved compilation error

I've an application that uses Maven to build a JAR with the maven-assembly-plugin.
The project includes a list of dependencies and one of these is another Maven project.
I'm developing with Eclipse and when I run the project everything works fine. When I build with the Maven goal assembly:assembly, it makes the JAR but when I run the JAR it gives me this error:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:

The problem is related to the Java mail dependency. As you can see I've used com.sun.mail but I saw some other different libraries that correspond to javax.mail.
Maybe I'm missing something in my poms, such as configuration parameters or plugins.
I've also tried to put in my local repository a mail.jar that works fine in other projects but I get the same error.

The "Unresolved compilation problem" comes from a class file in your utils project that Eclipse has compiled, but where Eclipse was unable to compile it properly.
The reason you are seeing different results from Eclipse and Maven is that they are using different versions of the class file. Eclipse is doing workspace resolution, so it's using the version of SMTPMailService in utils/target/classes. Maven is resolving the utils jar from your local Maven repository, which was put there by running mvn install while you had compile errors in Eclipse.
Try running mvn clean install in the utils project (clean to remove any class files generated by Eclipse, install to replace the jar in your local repository). Then rebuild your assembly.
