Classpath variables

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 the variable has to be configured on this page.


Command	Description
New...	Adds a new variable entry. In the resulting dialog, specify a name and path for the new variable. You can click the File or Folder buttons to browse for a path.
Edit...	Allows you to edit the selected variable entry. In the resulting dialog, edit the name and/or path for the variable. You can click the File or Folder buttons to browse for a path.
Remove	Removes the selected variable entry.

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.
