Including hibernate jar dependencies in ant build
- by Patrick
Hi,
I'm trying to compile a runnable jar-file for a project that makes use of hibernate. I'm trying to construct an ant build.xml file to streamline my build process, but I'm having troubles with the inclusion of the hibernate3.jar inside the final jar-file.
If I run the ant script I manage to include all my library jars, and they are put in the final jar-file's root. When I run the jar-file I get a
java.lang.NoClassDefFoundError: org/hibernate/Session
error. If I make use of the built-in export to jar in Eclipse, it works only if I choose "extract required libraries into jar". But that bloats the jar, and includes too much of my project (i.e. unit tests).
Below is my generated manifest:
Manifest-Version: 1.0
Main-Class: main.ServerImpl
Class-Path: ./ antlr-2.7.6.jar commons-collections-3.1.jar dom4j-1.6.1.jar
hibernate3.jar javassist-3.9.0.GA.jar jta-1.1.jar slf4j-api-1.5.11.jar
slf4j-simple-1.5.11.jar mysql-connector-java-5.1.12-bin.jar rmiio-2.0.2.jar
commons-logging-1.1.1.jar
And the part of the build.xml looks like this:
<target name="dist" depends="compile" description="Generates the Distribution Jar(s)">
<mkdir dir="${dist.dir}" />
<jar destfile="${dist.dir}/${dist.file.name}.jar" basedir="${build.prod.dir}" filesetmanifest="mergewithoutmain">
<manifest>
<attribute name="Main-Class" value="${main.class}" />
<attribute name="Class-Path" value="./ ${manifest.classpath} " />
<attribute name="Implementation-Title" value="${app.name}" />
<attribute name="Implementation-Version" value="${app.version}" />
<attribute name="Implementation-Vendor" value="${app.vendor}" />
</manifest>
<zipfileset refid="hibernatefiles" />
<zipfileset refid="slf4jfiles" />
<zipfileset refid="mysqlfiles" />
<zipfileset refid="commonsloggingfiles" />
<zipfileset refid="rmiiofiles" />
</jar>
</target>
The refids' for the zipfilesets point to the directories in a library directory lib in the root of the project. The manifest.classpath-variable takes the classpath of all those library jar-files, and flattens them with pathconvert and mapper.
I've also tried to set the manifest classpath to ".", "./" and only the library jar, but to no difference at all. I'm hoping there's a simple remedy to my problems...
