No. The JAR-spec [1] sais:
Main-Class :
The value of this attribute defines the relative path of the main
application class which the launcher
will load at startup time. The value must not have the .class extension
appended to the class name.
Class-Path :
The value of this attribute specifies the relative URLs of the extensions
or libraries that this
application or extension needs. URLs are separated by one or more spaces.
The application or extension
class loader uses the value of this attribute to construct its internal
search path.
Means:
"java -jar TidyTest.jar" adds TidyTest.jar to the classpath and looks into
TidyTest´s manifest for
a Main-Class attribute. If specified that class will be started.
Like
java -cp TidyTest.jar atreides.jtidy.TidyTest
But you need the Tidy.jar also, therefor you would start
java -cp TidyTest.jar;Tidy.jar atreides.jtidy.TidyTest
So you have to specify the Class-Path.
<target name="manifest" depends="compile">
<manifest file="${destdir}/MANIFEST.MF">
<attribute name="Main-Class"
value="atreides.monsters.${mainClass}" />
<attribute name="Class-Path" value="Tidy.jar" />
</manifest>
</target>
With that manifest Java searches for Tidy.jar in the directory of
TidyTest.jar.
