According to http://www.eclemma.org/jacoco/trunk/doc/offline.html, when doing offline instrumentation, I need to provide the original class files to generate the report. Exactly how do I do that with Maven? I know the original class file is saved under generated-classes folder so right now I'm just copying the generated-classes folder over the classes folder when running generating the report but is there a way to specify the original class file path within the POM file? I couldn't find any examples anywhere. Thanks!
jacoco-maven-plugin provides instrument that comes in a pair with restore-instrumented-classes. And there is an example of usage in JaCoCo documentation - http://www.jacoco.org/jacoco/trunk/doc/examples/build/pom-offline.xml

I'm currently programming a java programm in eclipse and have a java class file that can read Strings.
The file is not a system file and I'm looking for a solution to import that file without copying it into the project directory. Is there a posibility to do that in Java or in eclipse?
You can make that class a dependency using something like Maven: https://maven.apache.org/
OR
You can make a Jar from that class and add it to the classpath manually

We have a console program that checks all .java files in a project for some common mistakes. It Reads the source code as plain text. We'd like to transform it to a maven plugin that is run when pushed to gitlab in the CI pipeline
There is a description of writing Maven plugins here:
https://maven.apache.org/guides/plugin/guide-java-plugin-development.html
You need to use the packaging maven-plugin and extend the AbstractMojo class.

I am new to Java development and just saw a file with .bak extension that looks like a java class but it is not. So I am wondering what is the purpose of the .bak files in general and why and when should I use it?
There is no special purpose for java files (or tooling here).
bak typically resorts to backup.
Such files get generated by various tools. These tools create bak files to avoid overwriting your original file. So there is no specific notion towards "java technology" here.
Simply look into the tools (mainly: your editor), and see if their help tells you about automatically creating backup file. The old Windows notepad editor did that for example.

I have just downloaded a java library. It is zip file. After extracting I have found that it consists of jar files. Now what am I supposed to do with it? Where do I copy these files so that I can access them from the java code.
The is an excellent answer to that in a related question.
Basically you tell the compiler and/or the runtime explicitly where the jars are.
Good luck!
Actually, you can extract your libraries where ever you want, but I you have to pass their path as an arguments to the java and javac commands in order to compile and to run your application

How can I generate the API documentation for a certain project?
What do I need exactly? javadoc plugin? rt.jar?
Could anyone describe the whole process?
Right now, I am stucked here:
I have documented all my classes and methods with javadoc comments. When I try in Eclipse:
Project - Generate Javadoc -> Javadoc Command -> Configure -> C:\Program Files\Java\jre7\bin
and I CAN´T FIND javadoc.exe!
Is javadoc.exe included with the jre7?
Javadoc is not part of the JRE, but of the JDK.
