Classpath Variables Preferences
Configurable variables
Classpath variables can be used in a Java Build Path to avoid a reference to the local file system. Using a variable entry, the classpath only contains a variable and the
build path can be shared in a team.
The value of such variables is configured on the
Java > Build Path > Classpath Variables
preference page.

Reserved class path variables
Certain class path variables are set internally and can not be changed in the Classpath variables preferences:
-
JRE_LIB: The archive with the runtime JAR file for the currently used JRE.
-
JRE_SRC: The source archive for the currently used JRE.
-
JRE_SRCROOT: The root path in the source archive for the currently used JRE.
These variables are deprecated and should not be used anymore. Instead
use a JRE System Library.
