Some questions on Ant

Discussion in 'Java' started by subhabangalore@gmail.com, May 12, 2013.

    Dear Room,

    I was trying to learn Apache Ant.

    I got the following information.

    i)Ant is a build tool, it helps to create .exe file.
    ii) Compiling is a subtask of building.

    Now,
    I am confused with few questions.

    I was exploring the "Ant build" in Eclipse.

    I could create one "build.xml" and could run successfully.

    The questions are:
    i) May I have to write the the "build.xml" or a build file everytime I want to build a project? Can't it be done automatic, means the generation of the .xml file?

    ii) After the "build.xml" gives report like,

    Hello:
    [echo] Hello
    BUILD SUCCESSFUL
    Total time: 477 milliseconds

    Where may I find .exe file? And how should I use it?

    If any one of the learned members can kindly suggest?

    Regards,
    Subhabrata.

    You usually don't have exe files in Java, so it helps create
    jar/war/ear/rar files. And many other things.

    With the right content then you can reuse the same build.xml for
    multiple projects as long as they are similar and simple. For bigger
    project you typical need some custom work.

    Java is not build to exe files.

    You can use the jar task to build a jar file.

    And it will be located where you tell ant to put it.

    Thanks. I am checking the things. I found Lingpipe already has "build.xml" then why the room is asking me to get along with it, the other question pondering me it is not running like the one I experimented it is giving error as, BUILD FAILED
    C:\Users\subhabrata\Documents\lingpipe-4.1.0.tar\lingpipe-4.1.0\build.xml:50: Unable to find a javac compiler;
    com.sun.tools.javac.Main is not on the classpath.
    Perhaps JAVA_HOME does not point to the JDK.
    It is currently set to "C:\Program Files\Java\jre7"

    Total time: 896 milliseconds

    Regards,
    Subhabrata.

    I think the other respondents have suggested you need more
    experience with the Java programming environment. I agree.


    the other question pondering me it is not running like the one I
    experimented it is giving error as, BUILD FAILED

    Dear Sir,
    That is okay. I could place ant properly my machine can recognize ant in command prompt. Other than this as Sujit suggested I could run Lingpipe demo from command prompt. As you are kindly teaching me let me learn it too. I tried it but got the following error, I am trying still let me see where I land tomorrow evening.

    No, but every time you create a project or change how it builds you will need to add or modify
    the build.xml.

    Not really. You start with a standard build.xml and modify it.

    That's not how you invoke Ant. Read the instructions.

    Or type "ant --help" or "ant -h" or "man ant" at the command line.

    > Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre7\lib\tools.jar


    That's not a JDK. Install the JDK. Ant will not work with only the JRE. Youcannot build
    Java files with only the JRE. This is explained on the Java site. You should read the instructions.

    You need to fix your broken lines in your posts.

    Yes. You did not invoke Ant correctly.

    Usually you can run ant without setting classpath to Java.

    Dear Group(Thanks Lew),

    I found the error in another library named "MALLET", so trying the following way:

    First I changed JAVA_HOME environmental variable to point to C:\Program Files\Java\jdk1.7.0_05\lib\tools.jar

    Then I used the following command,

    C:\Program Files\Java\mallet-2.0.7>ant -version
    Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre7\lib\tools.jar
    Apache Ant(TM) version 1.8.2 compiled on December 20 2010

    am I going fine?

    Regards,
    Subhabrata

    NB: Sorry to post garbages, I'll try to keep a check. Thanks for the suggestion.

    JAVA_HOME should point to C:\Program Files\Java\jdk1.7.0_05 not
    C:\Program Files\Java\jdk1.7.0_05\lib\tools.jar !

    That is wrong!

    JAVA_HOME should indicate the *directory* where you installed the JDK.

    It should *not* point to a JAR file.

    > Then I used the following command,
    >

    This does not do a build.

    > Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre7\lib\tools.jar


    That is not where the tools.jar is. It should be in the JDK directory. You have not installed
    the JDK. Why did you ignore the advice to install the JDK?

    > Apache Ant(TM) version 1.8.2 compiled on December 20 2010
    >

    Absolutely not.

    Once again, as everyone keeps telling you, READ THE DIRECTIONS!

    Install the JDK. Point JAVA_HOME to where the JDK is installed, although it is not strictly needed.
    Keep the JDK command directory, where the "java" and "javac" commands reside, in your PATH.
    This command directory will be a subdirectory of the $JAVA_HOME directory, if that environment
    variable is set, or what would be that directory if you don't set the variable.

    Read the directions. Try following the advice you get here before asking another question.

    Furthermore, OP, you should use a current version of Java. 7u5 is far too old.

    The minor upgrades (7u21 is current) cover security and bug fixes. Do you want an insecure
    or buggy version?

    Dear Group,

    I read the URL

    "http://docs.oracle.com/javase/7/docs/technotes/tools/windows/classpath.h

    tml"

    I went to Computer--->Properties-->Advanced System Settings-->Environment

    Variables-->ANT_HOME/JAVA_HOME

    In JAVA_HOME Variable Value is now:
    "C:\Program Files (x86)\Java\jdk1.7.0_21"

    Updated to the latest JDK and ported Eclipse also with it.

    In ANT_HOME Variable Value is now:
    "C:\Program Files\Java\apache-ant-1.9.0"

    While installing it tried to follow:
    "http://ant.apache.org/manual/install.html"

    As I am giving

    C:\>Ant
    Buildfile: build.xml does not exist!
    Build failed

    C:\>ant -version
    Apache Ant(TM) version 1.9.0 compiled on March 5 2013

    C:\>ant -help
    .....
    .....

    .....
    these are working.

    Means "So Ant works."("http://ant.apache.org/manual/install.html")

    But, as I am giving
    C:\Program Files\Java\mallet-2.0.7>ant

    The build is still failed.

    I'm checking the things.

    I worked out following things:

    C:\Users\subhabrata\Documents\lingpipe-4.1.0.tar\lingpipe-4.1.0>ant
    Buildfile: C:\Users\subhabrata\Documents\lingpipe-4.1.0.tar\lingpipe-

    4.1.0\build
    ..xml

    compile:

    BUILD SUCCESSFUL
    Total time: 1 second

    C:\Users\subhabrata\Documents\lingpipe-4.1.0.tar\lingpipe-4.1.0>



    Regards,
    Subhabrata.

    That should be spelled "ant". Only the fact that Windows is weird about letter case
    saved you there.

    > Buildfile: build.xml does not exist!


    Read the directions. Where does the "ant" command find its build file?

    http://ant.apache.org/manual/running.html#commandline

    Read the directions.

    See how that works now that you've read the directions?

    What is that directory? What is in that directory? What are you trying to build?

    Dear Group,

    I would make a detailed study also. Thank you for your kind suggestion.
    But more or less all the ant commands on Lingpipe are working fine.
    The build is getting failed for another Library Mallet. The instructions are given here,("http://mallet.cs.umass.edu/download.php"), the kind of trouble you are taking I can not request you to suggest. I am trying to discuss the preliminary issues with MALLET forum, if I can not get much help I am getting back to you.

    Regards,
    Subhabrata.

    Is there a "build.xml" in that directory? Why did you ignore these questions I asked?

    >>> The build is still failed.


    And you have not answered my questions. Also, how did it fail? With what messages?

    >> What are you trying to build?


    Okay, I guess you're trying to build Mallet, but why? It's already built!

    Why are you building these projects if they're already built?

    Those instructions tell you to go ahead and just use Mallet. Couldn't you do that?

    Dear Group,

    Yes, it is fine now. There was a silly error.

    "mallet.jar" in the "dist" directory within Mallet is also created.

    But I can not do java -jar mallet-jar.

    Subhabrata.

    First of all, even if "mallet.jar" actually is an executable JAR, calling it "mallet-jar" will not
    execute it.

    http://docs.oracle.com/javase/7/docs/technotes/tools/windows/java.html#synopsis

    Second, even if you spell the JAR name correctly, if it isn't an executable JAR then it won't
    execute.
