Ant with Hudson

问题

I have problem in running the Job in Hudson. I have configured the Hudson with the ANT_HOME with the path of the ant and JDK as well with the relative path. And I created a New Job, where I setup the SVN path and rest of the things. My build.xml of the project is in Project root Folder/build/build.xml

And them I have added the build.xml in the Linux. Which is like this.

<project name="Test Job" default="build">
    <target name="clean">
        <delete dir="${basedir}/svn/_build"/>
        <delete dir="${basedir}/build"/>
    </target>
    <target name="prepare">
        <mkdir dir="${basedir}/svn/_build/logs"/>
        <mkdir dir="${basedir}/build/logs"/>
        <mkdir dir="${basedir}/build/docs"/>
    </target>
    <target name="build"
            depends="clean,prepare"/>
</project> 

Note : My I set my job name as usercentral.

Then I tried build now on Hudson. It is giving me the below error.

FATAL: command execution failed.Maybe you need to configure the job to choose one of your Ant installations?

回答1:

Append $ANT_HOME/bin to your existing PATH in order for Hudson to be able to look for the ant command... or at least, that's how I fixed my same exact problem.

回答2:

Give hudson the absolute path to your ant installation. You can do this in the configs. Then just use this ant installation in your builds. You won't have to give an ANT_HOME.

回答3:

First, I told Hudson to use some version of Ant that it automatically installed and give that version of Ant a name. (From the Ant part of the Manage Hudson->Configure System page)

Second, I told the new project which named Ant to use. (From the Invoke Ant part of the project configuration"

回答4:

Sounds like it could be a permissions issue. Does the hudson user have access to the directory path for all the relevant files and directories?
