So, i had my little programm running almost fine when suddenly my pc crashed and nothing was saved. Now my script is at a point where i simpely don't understand it anymore (as i am new to coding and in order to solve my problem i made it even worse), i just can't get it to work anymore.
This is my pom.xml file:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Before everything crashed and i messed up the code could do the following:
- It imported sikuli (i think this works just as any other jar. Btw, is there anything i can fuck up because i am using 1.1.0 but i found higher ones on maven but wasn't sure what to do with them);
- it imported my imgs folder (This is what my project looks in eclipse: http://prntscr.com/fa7kii)
- and it opened the App.java i programmed
Atm when i am running my App.java everything is fine, but i can't export it. The UI is not showing up (i think i did not set up mainclass properly); but i am trying to solve this problem now for like 3 hours and i simpely am that confused that i don't know what do do anymore. I deleted my code multiple times, and this is what's left over.
Could you please just fix my pom.xml file and explain me how?
I also have this under the overview: http://prntscr.com/fa7laj
I think i do have a few plugins installed, do i have to uninstall them?
Please help me, i am really confused...
I want to have a jar i can click and need nothing else, which then searches the image inside and clicks on it.
I do have the App.java code done, but i don't think it's required here.
Sorry for my bad english, i am from germany.
Bit more information(idk if required):
I am working with eclipse and maven. I do have a windows 7 pc.
Thank you!
Solved it. Thanks for downvoting.

I got this error when trying to configure a pom xml to start building a project, but I don't how to fix. I tried so hard, deleting and adding characters, but I didn't succeed.
It seems like, the problem is in the "plugins".
Does anyone have a tip?
Thank you in advance!

compare it with your previous code in a diff editor and read through andrewjames's comment. You will be able to work what was wrong previously.
I am using maven with netbeans. Whenever I run the program it gives me java.lang.NoClassDefFoundError exception even after adding javaee-api 8.0 to dependencies.
Here is my pom.xml:

I can see the javax.json.bind.* in Dependencies. I don't get why am I not able to run the program. Any pointers?
The problem you face is that you need to add libraries which you use in your project manually. As you said javaee-api has dependency to javax.json.bind.* but the scope of that is provided which means that it will provide by your jdk or a container (application server for example) in the runtime( for more information about scopes check this). So you need to add libraries you need as compile scope(the default scope) which you need them in runtime.
I am trying to follow the Maven in 5 Minutes tutorial for my project but for some reason I can't seem to actually run my project when it builds. I have the following pom.xml file:
<?xml version="1.0"?>

The tutorial seems to imply that I can do this from my project root:
mvn package
java -cp target/my-artifact-0.0.1-SNAPSHOT.jar com.my.package.MyClass
However, if I try to do this, I get the following error message:
Error: Could not find or load main class com.my.package.MyClass
If I run java -cp ../my-artifact-0.0.1-SNAPSHOT.jar com.my.package.MyClass from the target/classes directory I still get the same message, which is weird because I've verified that the .class file is there. Why am I not able to run my project after building it with the above steps?
I am writing an android library project and would like to add the support for maven. My library project pom file looks like this:

I am installing the library project to my local repository using:
mvn clean install
then I am compiling and installing the main project to my local repository using:
mvn clean install
and generating the apk using:
mvn android:deploy
Now the problem occurs when I compile the project with maven. The project compiles successfully, however when I am running the apk on the device I receive NullPointerException when trying to perform findById for resources that are inside the library project. Please note that part of the time findById does return value, but not always the correct type (e.g, expected layout but got a button). It is important to say that when running in eclipse without maven everything works perfectly.
Please advise
Finally I found the solution, so I'll update my answer for future readers.
The solution to this problem was to create aar file instead of apklib file using maven.
I am rather new to Maven and I am having trouble using it. I have a working Android app, which uses aChartEngine, that runs fine in Eclipse but I need to use Maven for testing. There has been a repository set up for ACE but I can't seem to access it properly. Here is my POM:

Is there something I'm doing wrong here? Let me know if I can add any more information.
Note that I am not using Maven from Eclipse, I am running it in a command prompt on windows 7.
UPDATE: I think I have found the problem but I'm not sure yet, so I'll still post the error message:
[ERROR] Failed to execute goal on project my-app: Could not resolve
dependencies for project com.mycompany:my-app:apk:0.0.1-
SNAPSHOT: Could not find artifact org.achartengine:achartengine:jar:1.1.0 in ...(my companies repository)
It turned out that the jar was not loaded into the repository that was being used. Got it all functional now.
