I have a maven project with some library dependencies (.dll) (which I put in a "lib" folder). I can run the project without problems in Netbeans, but when I try to run the built .jar outside of Netbeans, I get the following error on loading the library:
Can't load this .dll (machine code=0xbd) on a AMD 64-bit platform
I only have one instance of Java installed on my computer, it should be the same JVM that Netbeans/Maven uses to run the project. So I can't understand how Netbeans/Maven is able to run this application on a different platform than me? I've tried looking at the command Netbeans executes (from the output) to run the project and I think it's this:
cd C:\Users\Birger\Workspace\myproject; "JAVA_HOME=C:\\Program Files\\Java\\jdk1.8.0_91" cmd /c "\"\"C:\\Program Files\\NetBeans 8.1\\java\\maven\\bin\\mvn.bat\" -Dexec.args=\"-Djava.library.path=lib\\ -classpath %classpath com.mysite.myproject.Main\" -Dexec.executable=\"C:\\Program Files\\Java\\jdk1.8.0_91\\bin\\java.exe\" -Dmaven.ext.class.path=\"C:\\Program Files\\NetBeans 8.1\\java\\maven-nblib\\netbeans-eventspy.jar\" -Dfile.encoding=UTF-8 org.codehaus.mojo:exec-maven-plugin:1.2.1:exec\""
I tried these two commands
"C:\Program Files\Java\jdk1.8.0_91\jre\bin\java.exe" -Djava.library.path=lib\ -jar myproject-1.0-SNAPSHOT.jar
"C:\Program Files\Java\jdk1.8.0_91\bin\java.exe" -Djava.library.path=lib\ -jar myproject-1.0-SNAPSHOT.jar
I added System.out.println(System.getProperty("sun.arch.data.model")); to get my application to print out the cpu architecture. It prints 64 in both occasions.
Tried looking into the "mvn.bat" file in C:\Program Files\NetBeans 8.1\java\maven\bin\mvn.bat but I couldn't find any clues as to what Maven is doing to run my application.
Can somebody help me on this one?

EDIT2:
For anyone looking to reproduce this error, jni4net can be found here. I installed the .jar with this windows batch file:
set project_dir=YOURPROJECTDIRECTORYHERE
set proxygen_dir=YOURPROXYGENINSTALLATIONDIRECTORYHERE
set temp_repo_dir=%project_dir%\temp-repo

EDIT3:
I installed 32-bit JVM, and tried running the application with the following command:
"C:\Program Files (x86)\Java\jre1.8.0_91\bin\java.exe" -Djava.library.path=lib\ -jar myproject-1.0-SNAPSHOT.jar
Now I get:

I have faced this problem long time ago.
just remove the <filtering>true</filtering> ,this get the files corrupted while copying. (Bug !!???).
I was able to reproduce your issue. this will resolve your problem also
hope this helps.
