设置类路径并顺序调用jar

Question

I am trying to write a bash script to automate the work of executing my files for the grader in my class.

cd ReflectionJar
export CLASSPATH=.:$CLASSPATH:/MicahRamirez/out/artifacts/ReflectionJar/ReflectionJar.jar
java -jar ReflectionJar.jar Notepad ./MicahRamirez/ReflectionJar/otherclasses/Notepad
java -jar ReflectionJar.jar graff ./MicahRamirez/ReflectionJar/otherclasses/graff
java -jar ReflectionJar.jar quark ./MicahRamirez/ReflectionJar/otherclasses/quark
java -jar ReflectionJar.jar yparser         ./MicahRamirez/ReflectionJar/otherclasses/yparser
java -jar ReflectionJar.jar reflectionPackage ./ReflectionJar/MicahRamirez/otherclasses/reflectionPackage

Directiory Structure: DirectoryStructure Pic

I am currently receiving

./reflection.sh: line 4: export: `=': not a valid identifier
./reflection.sh: line 4: export: `./MicahRamirez/out/artifacts/ReflectionJar/ReflectionJar.jar': not a valid identifier
Error: Unable to access jarfile ReflectionJar.jar
...

My real roadblock are the first two errors. I have looked at quite a few SO posts to see how I would export the classpath and what I've found doesn't seem to work...

I've tried

 export CLASSPATH=$CLASSPATH:./MicahRamirez/out/artifacts/ReflectionJar/ReflectionJar.jar
 export CLASSPATH=./MicahRamirez/out/artifacts/ReflectionJar/ReflectionJar.jar

Neither have worked.

When you specify the -jar option, the classpath is taken from the Manifest file, and the environment variable and/or -cp command-line arguments are ignored. See documentation :

-jar

Executes a program encapsulated in a JAR file. The first argument is the name of a JAR file instead of a startup class name. For this option to work, the manifest of the JAR file must contain a line in the form Main-Class : classname . Here, classname identifies the class with the public static void main(String[] args) method that serves as your application's starting point.

When you use this option, the JAR file is the source of all user classes, and other user class path settings are ignored .
