Cannot find javahl, svnkit nor command line svn cl

问题:

I've done numerous svn / ant set-ups and but this time cann't figure out what's wrong.

Using Linux,

svn 1.6.6
ant 1.8.2
svnant 1.3.1

I've copied the svnant jar files into $ANT_HOME/lib

top@secret:~/apps/apache-ant-1.8.2/lib$ ls -l
-rw-r--r-- 1 root root  244831 2011-06-23 07:55 ganymed.jar
-rw-r--r-- 1 root root  948100 2011-06-23 07:55 jna.jar
-rw-r--r-- 1 root root   76383 2011-06-23 07:55 svnant.jar
-rw-r--r-- 1 root root  215757 2011-06-23 07:55 svnClientAdapter.jar
-rw-r--r-- 1 root root   89412 2011-06-23 07:55 svnjavahl.jar

etc...

My build file specifies:

<taskdef name="svn" classname="org.tigris.subversion.svnant.SvnTask"   />

But whenever I execute

   <target name="update">
                <svn>
                        <update dir="."/>
                </svn>
        </target>

I get the dreaded:

update:
      [svn] Missing 'javahl' dependencies on the classpath !

BUILD FAILED
/home/top/apps/utils/build.xml:26: Cannot find javahl, svnkit nor command line svn client

Any ideas what I'm doing wrong?

I assumed copying the svnant jars into $ANT_HOME/lib should be enough?

回答1:

Javahl way always needs some kind of os-dependent driver. This is mostly hard to set-up and I don't recommend using it.

You should try using svnkit:

<svn svnkit="true">

This uses the pure java library, but needs svnkit.jar to be in the classpath.

I only use the fallback/commandline version, where the svn executable is in the PATH. This works in most cases without problems with the following settings:

<svn svnkit="false" javahl="false">

Note: These settings are for svnant 1.31 and prior. Since version 1.32 you can use <svnSetting />, which is described in the other answer

回答2:

As of svnant 1.3.2 the attributes svnkit and javahl have been deprecated. The alternative is to use the svnSetting task.

Put this task in your build file somewhere:

<svnSetting
    svnkit="false"
    javahl="false"
    id="svn.settings"/>

Then when you are calling the svn task use it this way (take note of the refid attribute):

<target name="doingSomethingAwesome">
    <svn refid="svn.settings">
        <!-- do something -->
    </svn>
</target>

Hope this helps, did me.

If you are getting "Cannot find javahl, svnkit nor command line svn client" then you have to make ensure that svn path have been set or not : for exa : path=c:\svn\bin;
