One jar build example help

  • James

    James - 2013-03-06

    I am just confused one running the build with ant that does not find the build.xml

    and running the hello world example from the readme file. that Could not find or load main class com.simontuffs.onejar.Boot

    and running the one-jar-sdk-0.97.jar that I had to change to zip and extract the file because it would not expand.

    any hints to make progress on any of these concepts would be helpful
    thanks :

    is ant supposed to be able to be called from anywhere?

    C:\Users\Steves>cd %ANT_HOME%
    C:\ant\apache-ant-1.8.1>cd bin
    C:\ant\apache-ant-1.8.1\bin>ant -version
    Apache Ant version 1.8.1 compiled on April 30 2010

    As you can see the sdk dir above shows a build.xml

    C:\ant\apache-ant-1.8.1\bin>echo %BUILD%
    C:\ant\apache-ant-1.8.1\bin>ant %BUILD%
    Buildfile: build.xml does not exist!
    Build failed

    this might help when I get the chance to run it

    So where is the build.xml file? If it's not in the directory where you're executing the command, then you need to tell Ant where to find it using the "-file" switch.

    I have to give up on ONEJAR for now.

    I have to hit the ANT DOCS and school my self on the build.xml.

    I will have to revisit ONEJAR after I lean to flatten a lib of dependecies and

    build an application to create a dist executable jar file and then maybe the one

    jar instructions will make sense to me.

    because simple stuff like :

    The quick start doc is missing switches in the ant hello ? the SDK does not


    the build built once succefully to some dir from some MANIFEST and no jar file

    ran correctly.

    So  nothing worked for me in the quick start or README.txt instructions.

    and the app generator generated something for eclipse. So by the time I get

    one jar to run an hello.jar I will have to re config the build.xml to get my app

    to provide a dist exe jar anyway.

    I can not expect to correctly install a program I wrote unless I learn ANT.

    great learning experience though. It offered a lot of good questions that I did

    not know to ask. Now, to solve them.

    thanks for your time

    Thanks, I appreciate your persistence and your feedback. I think the biggest strength of one-jar is also its weakness here: it's a programming tool which requires quite a high level of sophistication and knowledge of other tools. 

    You might want to look at the Eclipse jar exporter that was contributed by Ference Hechler.  It's in Eclipse (3.6 and later I think), and it uses a clever approach (similar to one-jar, but actually better in some ways) to take an Eclipse project and all its dependencies, and produce a single jar with embedded jars.  I recall that you are a Netbeans user so this might not be attractive, but it might help you get your project deployed. 

    I have considered wrapping a UI around one-jar to help mitigate the learning curve, but I just don't have the time.  I hope somebody can step up to this in the future.

    Thanks for  all your help and patience. I would like to make my next program be a GUI to handle all the
    Requirements to flatten the Applications.  I will have to get over the ANT learning curve to find out every
    Thing possible with the build file. I am trying to learning what needs to happen to make a .exec file and
    You have helped with your ONE JAR program and with all your assistance . Thanks .
