Ant: Problem: failed to create task or type propertyregex

ant

I'm using Ant 1.8.1. I have downloaded ant-contrib-1.0b3.jar and placed it in my $ANT_HOME/lib directory. However, when I include this in my build.xml file …

<propertyregex property="selenium.email.success.subject"
          input="package.ABC.name"
          regexp="(.*)__ENV__(.*)"
          replace="\1${buildtarget}\2"
          override="true"
          casesensitive="false" />

I get the error "Problem: failed to create task or type propertyregex. Cause: The name is undefined." upon running my Ant build file. What else do I need to do to get this task recognized?

The propertyregex ant task is part of ant-contrib, and not included by default in any apache-ant installation.

You have to properly install ant-contrib. From the ant-contrib page, you have two choices:

Copy ant-contrib-0.3.jar to the lib directory of your Ant installation. If you want to use one of the tasks in your own project, add the line <taskdef resource="net/sf/antcontrib/antcontrib.properties"/> to your build file.

Keep ant-contrib-0.3.jar in a separate location. You now have to tell Ant explicitly where to find it (say in /usr/share/java/lib):

<taskdef resource="net/sf/antcontrib/antcontrib.properties">
<classpath>
<pathelement location="/usr/share/java/lib/ant-contrib-0.3.jar"/>
</classpath>
</taskdef>

Ant: failed to create task or type

I've struggled with this for two days now. The answer I appear to be getting is implied by http://ant.apache.org/manual/tutorial-writing-tasks.html:

The <taskdef name="sqlscriptpreprocessor" ...> element must be placed down inside the target that uses it, in this case, mysql-preprocess. I was not doing this. Now, I have:

<target name="mysql-preprocess"
        description="Preprocess MySQL database scripts into one file">
    <taskdef name="sqlscriptpreprocessor"
             classname="com.etretatlogiciels.ant.task.SqlScriptPreprocessor"
             classpath="${basedir}/lib/ant-tasks/sqlscriptpreprocessor.jar" />
    <sqlscriptpreprocessor inputfilepath="${basedir}/extras/blackpearl.sql.in"
                          outputfilepath="${basedir}/extras/blackpearl.sql" />
</target>

I don't understand why my custom task must be defined in the target element that consumes it, but this is fine by me. I'm not certain this is couched as gracefully as it could be, but it works now.

I'm sorry for answering my own question; it's happened before once or twice and it seems pretty lame of me. I just hope it helps someone else.

Thanks for all the replies surrounding this topic in all the forums and posts I read over the last two days.

Java – Switch Statement gives Incompatible Types error

switch(name)

switch statement with String is supported from Java7 onwards only.

I guess the compiler version you are using is less than Java7

Options:

You need to either upgrade to Java7
Change switch statement to if/else
Use int in switch instead of String
