Too long line in manifest file while trying to create jar

Question

I am getting a too long line error while trying to build a jar. the long line in the manifest file is the Class-Path line as the application uses a lot of third-party libra

Answer 1

The classpath is too long due to the number of jar files in it. «No line may be longer than 72 bytes (not characters), in its UTF8-encoded form.» [from docs: java 5, java 8; «Line length» section].

use as the following way to resolve the problem:

(1) use separate lines, to avoid too long a line for java package name lists

(2) type a preceding space before each folloing lines, for example:

Class-Path:
 ...jar
 ...jar
 ...jar
