Browserstack automate-maven-plugin not working - maven

I'm trying to run my appium test on the BrowserStack device cloud with the use of Jenkins.
After adding the dependencies to my pom.xml mentioned in the following section
https://www.browserstack.com/app-automate/appium/jenkins#reporting
I received the following error:
[ERROR] Failed to execute goal com.browserstack:automate-maven-plugin:1.0.0-SNAPSHOT:test-compile (default) on project 1.0: Execution default of goal com.browserstack:automate-maven-plugin:1.0.0-SNAPSHOT:test-compile failed: Plugin com.browserstack:automate-maven-plugin:1.0.0-SNAPSHOT or one of its dependencies could not be resolved: The following artifacts could not be resolved: org.codehaus.mojo:aspectj-maven-plugin:jar:${aspectj.maven.version}, org.aspectj:aspectjtools:jar:${aspectj.tools.version}: Could not find artifact org.codehaus.mojo:aspectj-maven-plugin:jar:${aspectj.maven.version} in central (https://repo.maven.apache.org/maven2) -> [Help 1]

Can anyone help me with this problem?

you need to mention the jdk source and the targer versions here.

That's because BrowserStack repository no longer have a snapshot feature so you need to include the plugin as follows. You can check this answer for more on snapshot
<groupId>com.browserstack</groupId>
<artifactId>automate-maven-plugin</artifactId>
<version>1.0.0</version>
Without the SNAPSHOT

How to add and artifact located at openhab repository with Maven?

I am looking to add a dependency to my pom.xml file
The dependency is a library allowing to manipulate Bluetooth Low Energy devices. Here is the link : TinyB
Here is also the github of the library : intel-iot-devkit/tinyb
When I copy and paste the snippet code to add the dependency, I get the following error after Maven tries to resolve the dependencies :
Could not find artifact intel-iot-devkit:tinyb:pom:0.5.1 in central (https://repo.maven.apache.org/maven2)
Could this be because the artifact is located in the OpenHab repository ? Then if this may cause the problem, how to solve it ?
Here is a copy of my pom.xml file :
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

And here is the code snippet I added to pom.xml :
<dependency>
<groupId>intel-iot-devkit</groupId>
<artifactId>tinyb</artifactId>
<version>0.5.1</version>
</dependency>
There is a second repository where it is possible to use this library by adding a dependency to the pom.xml file. Indeed it seems that the libraries are stored on the repository of openHAB.
To proceed you must first :
Add a repositories section in the pom.xml file
Here is a snippet code:
<repositories>
<repository>
<id>openHAB</id>
<name>openHabTinyB</name>
<url>https://openhab.jfrog.io/openhab/libs-release/</url>
</repository>
</repositories>
You have to add the following dependency:
Here is a snippet code:
<!-- https://mvnrepository.com/artifact/org.openhab.osgiify/intel-iot-devkit.tinyb -->
<dependency>
<groupId>org.openhab.osgiify</groupId>
<artifactId>intel-iot-devkit.tinyb</artifactId>

How to use groovy-maven-plugin with groovy 3.0.x?

As per groovy-maven-plugin documentation it is possible to specify a particular groovy version to be used in a maven build. This succeeds with groovy-all versions up to 2.4.9, but version 2.5.0 or higher will break the build with the followin message, when I call "mvn validate":
[ERROR] Failed to execute goal org.codehaus.gmaven:groovy-maven-plugin:2.1.1:execute (default) on project groovy3demo: Execution default of goal org.codehaus.gmaven:groovy-maven-plugin:2.1.1:execute failed: Plugin org.codehaus.gmaven:groovy-maven-plugin:2.1.1 or one of its dependencies could not be resolved: Could not find artifact org.codehaus.groovy:groovy-all:jar:3.0.6 in central (https://repo.maven.apache.org/maven2) -> [Help 1]
The reason is that there is no 'groovy-all-3.0.6.jar' here in mavencentral repo. Apparently the 'groovy-all-<version>.jar is no longer deployed since version 2.5.0-beta3, only sources and javadoc. Version 2.4.9 seems to be the latest version that succeeds.
So my question is: How can I use groovy 3.x in my maven build?
Thank you for any hint.
Here is my pom.xml and (besides a maven installation) you don't need more than that to reproduce the problem:

Due to the changes introduced with groovy v2.5 and described with Release notes for Groovy 2.5 and GROOVY-8750, you should now use either the base groovy package or the wanted groovy modules, like:
<plugin>
<groupId>org.codehaus.gmaven</groupId>
<artifactId>groovy-maven-plugin</artifactId>
<version>2.1.1</version>
<dependencies>
<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-xml</artifactId>
<version>3.0.6</version>
</dependency>
</dependencies>
...
</plugin>
To work with all groovy modules you can also use groovy-all dependency
<plugin>
<groupId>org.codehaus.gmaven</groupId>
<artifactId>groovy-maven-plugin</artifactId>
<version>2.1.1</version>
<dependencies>
<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-all</artifactId>
<version>3.0.7</version>
<type>pom</type>
</dependency>
</dependencies>
</plugin>

No schemas have been found - Spring Boot WS

This is a screenshot how is look like the error:
Any help is appreciated!
Ok, if someone has the same error, I got the solution like this:
First, I configured the maven user settings in eclipse by adding a separate repository folder for the related project (Override the default path located in X:\Users\User.m2\repository).
I removed two custom profiles that I had in the previous file.
I updated the project and magically, the error disappeared.
Thanks to all for the help.

Flexmojos-maven-plugin - How to configure multiple source mxml files to generate multiple swf files?

Current working code:
I am able to build a flex project using flexmojos-maven-plugin successfully. However, I can only provide one 'sourceFile' under my plugin configuration. Refer below my working pom.xml, which builds Main.mxml file correctly from 'src' directory. It generates the 'swf' file for Main.mxml successfully:

Problem description:
Now I have got multiple other mxml files under my 'src' directory, i.e. all mxml files under one single 'src' directory. How do I add them in above plugin, which only expects one single name in sourceFile configuration?
Things I have tried:
I tried copy-pasting multiple blocks of flexmojos-maven-plugin, and each of them having different sourceFile specified. However, that does not help, because maven just generates the final 'swf' file from the last block of flexmojos-maven-plugin. For eg. if first plugin block has sourceFile Main.mxml, and second plugin block has sourceFile Secondary.mxml, then the 'swf' will be generated for Secondary.mxml only, not for Main.mxml.
Could you provide any other suggestions to generate individual swf files for respective mxml files using single pom/maven build?
After quite a lot of R&D, trying a few hacks, and based on valuable suggestion of Christofer Dutz on this forum, finally a clean solution is available for above problem. Here is the updated pom.xml, which will generate the individual swf files for provided source files:

Important note: You have to provide the ID of any one of the executions as 'default-compile-swf', without which it would fail to identify the source file. For more information on the error which it will throw, refer to the link of the forum given above where I was discussing the same.
Hope this helps someone someday :)

I don't know if this is tess4j related or a JNA/JNI problem, as you can see I have a plugin that "should" (never worked with DLLs before) make them work.
Also in the parent pom my plugin are betwen plugin managment tags, I think I should have put them betwen build tags, no?
Any idea?
Thanks.
There was 2 problems
1/ some dlls and files from tess4j had to be copied to the project root directory
2/ tess4j had a transitive dependancy toward com.sun.jna:jna:jar:3.0.9 conflicting with net.java.dev.jna:jna:jar:4.1.0 (also from tess4j) ecluding the 3.0.9 version makes everything work, the RESSOURCE_PREFIX error was coming from that
pom.xml for 32 bit version (you need a 32 bit JVM installed) which takes care of those 2 things, change win32-x86 to win32-x86-64 if you want to use this in 64 bits

The child pom could be easily built without any problems and manually copying libs, this is not TESS4J related.
Anyway the jna 3.0.9 could be removed if not needed anymore: https://github.com/nguyenq/tess4j/issues/8
Still, all you have to do to run tess4j is the maven dependency:
<dependency>
<groupId>net.sourceforge.tess4j</groupId>
<artifactId>tess4j</artifactId>
<version>1.4.1</version>
</dependency>
and the correct use of the TESS4J-API, for example:
File imageFile = new File("C:\\random.png");
Tesseract instance = Tesseract.getInstance();
//In case you don't have your own tessdata, let it also be extracted for you
File tessDataFolder = LoadLibs.extractTessResources("tessdata");
//Set the tessdata path
instance.setDatapath(tessDataFolder.getAbsolutePath());
try {
String result = instance.doOCR(imageFile);
System.out.println(result);
} catch (TesseractException e) {
System.err.println(e.getMessage());
}
That's it!
The problem is caused by the conflict between net.java.dev.jna:jna and com.sun.jna:jna. Both jars contain a class com.sun.jna.Platform. Both jars are declared as tess4j dependencies. To solve this you can omit the second dependency in your pom:
<dependency>
<groupId>net.sourceforge.tess4j</groupId>
<artifactId>tess4j</artifactId>
<version>1.4.1</version>
<exclusions>
<exclusion>
<groupId>com.sun.jna</groupId>
<artifactId>jna</artifactId>
</exclusion>
</exclusions>
</dependency>
because the JNA version mismatch. you are using more than one version in class path library. just use one version of JNA.
