"jdeps jar_file" - Dependencies of JAR File

This section provides a tutorial example on how to use 'jdeps' command to show package level dependencies of a given JAR file.



If you want to know package level dependencies of a given JAR file, you can run the "jdeps jar_file" command.

Let's use the JAR file, jrt-fs.jar, in JDK 12 as an example:

C:\herong>jdeps "\Program Files\Java\jdk-12.0.1\lib\jrt-fs.jar"

Warning: split package: jdk.internal.jimage jrt:/java.base 
   \Program Files\Java\jdk-12.0.1\lib\jrt-fs.jar
   
Warning: split package: jdk.internal.jimage.decompressor jrt:/java.base 
   \Program Files\Java\jdk-12.0.1\lib\jrt-fs.jar
   
Warning: split package: jdk.internal.jrtfs jrt:/java.base 
   \Program Files\Java\jdk-12.0.1\lib\jrt-fs.jar
   
jrt-fs.jar -> java.base
   jdk.internal.jimage   -> java.io                            java.base
   jdk.internal.jimage   -> java.lang                          java.base
   jdk.internal.jimage   -> java.lang.invoke                   java.base
   jdk.internal.jimage   -> java.lang.ref                      java.base
   jdk.internal.jimage   -> java.lang.reflect                  java.base
   jdk.internal.jimage   -> java.nio                           java.base
   jdk.internal.jimage   -> java.nio.channels                  java.base
   jdk.internal.jimage   -> java.nio.file                      java.base
   jdk.internal.jimage   -> java.nio.file.attribute            java.base
   jdk.internal.jimage   -> java.security                      java.base
   jdk.internal.jimage   -> java.util                          java.base
   jdk.internal.jimage   -> java.util.concurrent               java.base
   jdk.internal.jimage   -> java.util.function                 java.base
   jdk.internal.jimage   -> java.util.stream                   java.base
   jdk.internal.jimage   -> jdk.internal.jimage.decompressor   jrt-fs.jar
   ...

The output tells us that:

If you want to see class level dependencies, you use the "jdeps -verbose jar_file" command.
