Setting up Selenium correctly

I have been trying to install Selenium for about a day now, and I can´t get it to work. First, I just downloaded the standalone jar and added it as a user library. That did work out fine, until I wanted to use org.openqa.selenium.htmlunit.HtmlUnitDriver. Apparently, this library is not included in the jar.
So I downloaded the jar file for the htmlUnitDriver seperately. That did not work out at all, as I got an error in line 1 saying, that some library is "indirectly referenced from required .class files".
I deinstalled the libraries again and tried it with Maven. I included dependencies for selenium and the selenium htmlUnitDriver (as it again was not included).
But that still left me with the same problem. Below is my pom.xml file and the exact error message.
<project xmlns="http://maven.apache.org/POM/4.0.0"

WebDriver driver = new HtmlUnitDriver();
}
}
The error message:
I have noticed, that the error only occurs, when I initialise a WebDriver as a HtmlUnitDriver. Otherwise it is still shown, but not marked as an error:

There was a change one year ago which removes a list of interfaces. Those interfaces are used (implemented) by HtmlUnitDriver. The change was delivered in selenium-4.0.0-alpha-7 release.
So the solution would be to use Selenium release prior to mentioned one.
Either: (this is not stable version with some features of Selenium 4)

The latter is the most stable and recent version of Selenium 3.

The package com.google.inject is accessible from more than one module

I'm trying to upgrade an application to Java 11.0.2, from Java 8. So those are my very first steps with Jigsaw modules!
My application uses Guice, and the Assistedinject, and Throwingproviders extensions.
Here's my current module-info.java:
`
module com.example.mymodule {
requires com.google.guice;
requires com.google.guice.extensions.assistedinject;
requires com.google.guice.extensions.throwingproviders;
//...
}
`
The application is based on Maven and when I run mvn package I get no error. But In Eclipse (2018-12), I have this error "`The package com.google.inject is accessible from more than one module":
I tried commenting each of the required module in module-info.java but I clearly need the three of them.
Is there something I can do to remove this error? Or is this an Eclipse bug?

Here is a minimal project to reproduce my error.
And here's a video of the issue (to be watched in 1080P for clarity!).

Eclipse uses its own compiler which is even stricter than javac in following the specs. You are requiring different Modules/Jars in your module-info which are all using the package com.google.inject. This is some kind of a split package situation which is not allowed in the JPMS spec. AFAIK javac only yields an error if there are actual classes in the same packages of different moduls, but the eclipse compiler is even more picky here.
There are some solutions out there for solving split package problems. If you don't find a newer version of the libs where the problem is solved (which unfortunately is not very likely for most dependencies today) you could f.e. merge the modules into one custom modules, but this is not a perfect solution of course.
For more background information on the issue see also
Eclipse can't find XML related classes after switching build path to JDK 10 and https://bugs.openjdk.java.net/browse/JDK-8215739

I can reproduce the error on my machine (same Eclipse version, OpenJDK 11), works fine on Apache NetBeans IDE 10.0.
Seems to be a bug in Eclipse, you should file it here. You already have a minimal project that reproduces the error, that helps a lot.

Your test project already works in RC2 of 4.11 (which will be released on March 20, 2019)
You can download the release candidate at https://download.eclipse.org/eclipse/downloads/drops4/S-4.11RC2-201903070500/

Better way to deal with this kind of problem by just go to dependencies hierarchy in pom.xml, where you can find duplicate jar, sometimes it could be difficult to find duplicate jar as jar itself have pom dependencies and "Dependencies hierarchy" will help you to deal with maven problem

Unable to import any javax-servlet in Maven project in Netbeans

I am making a Maven project it is my first time with Maven. I'm using Netbeans and Tomcat server and I am not able to import any javax.servlet e.g. import javax.servlet.RequestDispatcher; etc. It looks like that:
There is info: javax.servlet does not exist and a solution proposed by Netbeans is for example: "Search Dependency at Maven Repository for javax.servlet.RequestDispatcher. When I click it then there is a pop-up window without anything to do:
I have the pom.xml file located in C://pathToNetbeansProjects/myProject/pom.xml
and I added a dependency for javax-servlet now my pom.xml looks like this:

I have no more ideas if I am doing something wrong with my pom.xml or maybe I need to do something in Netbeans to make it work. But I don't know really what.

The problem is 99% caused by a different import done by Maven on that library.
Maven imports your libs following a hierarchical manner, so probably there's some lib that you have imported that contains the javax.servlet, but it's not the version that you need.
First I suggest you to looking for which one is doing that for resolving the conflict by looking into maven hierarchy, you can achieve this with console command mvn dependency:tree -Dverbose ( look here for an example).
Then you can omit the unwanted libraries by a specific maven command inside your library:
<dependency>
....
<exclusions>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
</exclusion>
</exclusions>
</dependency>
This is an explanation useful for understanding "why" is happening this, so you can understand it.
Btw a quick fix, that you can try as first instance, is moving the import you wanted
javax.servlet as first element of your pom.

Force update your maven project or run
mvn clean install
on your project's directory to download all dependency of pom.xml. Build your project then and javax-servlet will be available.

Maven TinyB failure: package tinyb does not exist

I am trying to do a program where I need using Aws sdk and TinyB library. FOr that reason I have decided to use maven to create the project and resolve the dependencies. However, I have been trying to compile the project with the package TinyB for more than a week without success. I would be very grateful if someone could teach me what I am doing wrong.
The failure message I am receving is the following:

I have opened the project with Eclipse IDE to know what is happening but I have seen that eclipse is recognizing the dependencies correctly.
TinyB dependencie scan
Project dependencies
TinyB library I have downloaded and compiled the source from here:
https://github.com/intel-iot-devkit/tinyb
But there is no maven repositories directly from intel so I have added the one form eclipse kura:
<!-- https://mvnrepository.com/artifact/org.sputnikdev/bluetooth-manager-tinyb -->
<dependency>
<groupId>org.sputnikdev</groupId>
<artifactId>bluetooth-manager-tinyb</artifactId>
<version>1.0</version>
</dependency>
This one gives me problems when compiling, it seems as if the repository hasn't been downloaded. But the foder with the jar exists (it shows the error quoted previously).
I have made some little programs with TinyB and they are working perfectly, so the program is compiled and installed correctly. The problem is I am not using maven in this little programs (I just add the import and point to the .jar when executing). Like this:
sudo java -cp examples/java/HelloTinyB.jar:/usr/lib/lib/java/tinyb.jar HelloTinyB
I have also try this other maven repository:
<!-- https://mvnrepository.com/artifact/org.sputnikdev/bluetooth-manager-tinyb -->
<dependency>
<groupId>org.sputnikdev</groupId>
<artifactId>bluetooth-manager-tinyb</artifactId>
<version>1.3.2</version>
</dependency>
In this case it recognizes the dependencies and compiles. The problem is it gives error when I try to execute the program:
java.lang.RuntimeException: Native library is out of date. Please update the native library.
at tinyb.BluetoothManager.getBluetoothManager (BluetoothManager.java:317)
Thank you very much for your help.

I see you are trying to use eclipse Kura too.
Did you achieve making it work?
I have the same issue.
By the way, I see that maybe your dependencies are not really valid, as sputnikdev has a library over tinyB, but, finally I have the same problem than you. These are my main dependencies:
<!-- https://mvnrepository.com/artifact/org.sputnikdev/org.eclipse.smarthome.binding.bluetooth.transport.tinyb -->
<dependency>
<groupId>org.sputnikdev</groupId>
<artifactId>bluetooth-manager</artifactId>

The import org.springframework.test.context.junit4.SpringJUnit4ClassRunner cannot be resolved

I'm a newbie at Spring and this is also my very first question on StackOverflow so I'm going to try to make this as understandable as possible.
I'm trying to make a web service client using Spring and Maven on this tutorial: and I get this error: The import org.springframework.test.context.junit4 cannot be resolved

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; //this won't import
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = WsClientApplication.class)
public class WsClientApplicationTests {

You need to add a dependency on spring-boot-starter-test:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>

Now, if you are using latest spring-boot, 1.5.2 RELEASE, #SpringApplicationConfiguration is no longer available, instead you must use #SpringBootTest. Reference here(#spring boot starter test in Spring Boot)

Gradle
In gradle this would be done by adding
testCompile("org.springframework.boot:spring-boot-starter-test")
to the dependencies block as in:
dependencies {
compile("org.springframework.boot:spring-boot-starter-web")
testCompile("junit:junit")
testCompile("org.springframework.boot:spring-boot-starter-test")
}
After that it should be possible to write an import statement at the top of your class
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
Allowing you to use the annotation:
#RunWith(SpringJUnit4ClassRunner.class)
public class MyAppTest {
}

I know this is answered kind of late, but I had the same problem and I found I was able to fix it 2 ways.
I was able to remove the < scope > test < / scope> tags and that removed the restriction
I had an issue with intellij not properly handling it when doing tests, so I made sure it was marked as test-root, I changed it from green -> gray -> back to the green test-root and that resolved my issue.

Just to improve in the situation.
I managed to fix it like this:
before, spring boot initializr created a dependency to spring-boot-starter-test but with the exclusion, like this:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
<exclusions>
<exclusion>
<groupId>org.junit.vintage</groupId>
<artifactId>junit-vintage-engine</artifactId>
</exclusion>
</exclusions>
</dependency>
Eclipse accused the annotation #Runwith to be Junit 4, therefore, the logic thing to do was to remove the exclusion.
Final POM dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>

sometimes maven start downloading dependencies and doesn't finish.
Go to your .m2 folder and type:
find . -name *progre*
this command will show you every file with the tag "in-progess", which are the files missing or not finished.
delete the folder and try to update the dependencies again.

In case, you are not using the spring boot, but only spring framework you should add dependency for spring-test.
<!-- https://mvnrepository.com/artifact/org.springframework/spring-test -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>2.5</version>
<scope>test</scope>
</dependency>
You can check the latest version for spring-test using mvn, and update accordingly.
If you are using spring-boot project than add spring boot dependency, if you are not using spring-boot the below will work, but not recommended.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
<version>2.4.1</version>
</dependency>
NOTE: If you are using spring-boot project, adding <version> will not be necessary.
