HOWTO generate a JAR with manifest but without META-INF

[Jorg Panzer <j-...@t-online.de>]

hi,

i generate a jar include a manifest-file with:

[...]
     <dependencies>

     <dependency>
       <groupId>com</groupId>
       <artifactId>db4o</artifactId>
       <version>5.0</version>
       <scope>compile</scope>
     </dependency>

   </dependencies>

[...]

   <build>
     <plugins>

       <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-jar-plugin</artifactId>
         <configuration>
           <archive>
             <manifest>
               <mainClass>org.fhh.admin.Start</mainClass>
               <addClasspath>true</addClasspath>
             </manifest>
           </archive>
         </configuration>
       </plugin>

     </plugins>
   </build>

[...]




In the generated JAR-File is a META-INF including zu manifest.fm  
(Main-Class and ClassPath is OK), all sources and 3rd party JARs,  
like this:

my.jar
    |
    |---class1
    |
    |---class...n
    |
    |---jar1
    |
    |---jar...n
    |
    |---META-INF
		|
		|---manifest.mf


The problem is, the JAR isn't executable. The manifest.mf must placed  
a level higher ...

What can i do to create a JAR in the following structure ?

my.jar
    |
    |---classe1
    |
    |---class...n
    |
    |---jar1
    |
    |---jar...n
    |
    |---manifest.mf


Thanks...

False, the manifest must be in META-INF/ according to jar specifications:
http://java.sun.com/j2se/1.4.2/docs/guide/jar/jar.html

You problem is that your manifest is named 'manifest.mf' while it should
be named 'MANIFEST.MF', could it be you use a case insensitive
filesystem and there is already a manifest.mf (in which case when maven
tries to open MANIFEST.MF, filesystem opens manifest.mf)?
