Including All the Jars in a Directory Within the Java Classpath

Adding multiple jars to classpath on commandline

Remove the spaces from the classpath and add the current path

javac -cp jar/A.jar:jar/B.jar:jar/C.jar:jar/D.jar:. MyFile.java

Since Java 6 you can use classpath wilcards

javac -cp jar/*:. MyFile.java

Running Java command including all JARs in current folder

You've answered your own question, sort of.

. means that it will look for .class files in the current directory.

JARs act just like a directory. So to have the abc.jar "directory" you would specify abc.jar in your classpath.

If you need both the .class files present in the current directory, and the .class files packaged into JARs found in the current directory, you would have the following classpath: -cp ".:*.jar

All the answers here are telling you to use the wildcard without extension (* or ./*) but this is a bad practice, you don't want Java to go look into irrelevant files, so specify the extension: *.jar.

javac classpath option with multiple jar files in current directory causing error

The quoted sources for the two links provided in the comments as well as in the "This question may already have an answer here:", do not completely explain the observed behavior.

javac -cp ./*.jar MyFile.java

Won't work, because the wildcard * usage in this context differs from normal usage. This can be understood from the documentation. * always represents full file(s) and not partial file names.

javac -cp ./* MyFile.java

Should have worked. Apparently using double quotes and/or a semi-colon in windows. works:

javac -cp "./*" MyFile.java

javac -cp ./*; MyFile.java

javac -cp "./*;" MyFile.java

javac -cp *; MyFile.java

javac -cp "*" MyFile.java

javac -cp "*;" MyFile.java

Nowhere in the documention is this important fact mentioned afaik.

So I guess ON WINDOWS 7 64 bit, with java 1.6.0_75 EITHER USE DOUBLE QUOTES OR ALWAYS A SEMI-COLON WHEN USING WILDCARD *

set java classpath to multiple folders that have jar files and run from command line

Here is the solution that finally worked as expected. When the '*' character is used in the classpath for my specific scenario, it skipped everything after the first path. Using the double quotes(") for each path separately and then using ";" as the delimiter is the solution.

Having any space before or after the semi-colon ";" will also not work

javac -verbose -classpath "C:\Program Files\lib\java\core\*";"C:\Program Files\lib\java\core\locale\*";"C:\Program Files\lib\java\modules\*";"C:\Program Files\lib\java\modules\ext\*" testClass.java

Add all jar files to java classpath except of some ones

In Linux or OS X using this will do the job:

ls -1 $PWD/foo/*.jar | grep -v 'unwanted1.jar\|unwanted2.jar' | tr '\n' ':'

So you can use it together with java command:

java -cp `ls -1 $PWD/foo/*.jar | grep -v 'unwanted.jar\|unwanted2.jar' | tr '\n' ':'` ...

Set folder for classpath

If you are using Java 6 or higher you can use wildcards of this form:

java -classpath ".;c:\mylibs\*;c:\extlibs\*" MyApp

If you would like to add all subdirectories: lib\a\, lib\b\, lib\c\, there is no mechanism for this in except:

java -classpath ".;c:\lib\a\*;c:\lib\b\*;c:\lib\c\*" MyApp

There is nothing like lib\*\* or lib\** wildcard for the kind of job you want to be done.
