Hi There
I am currently blocked with not being able to build after upgrading ant
to the latest version. The errors I am getting are below.
If anyone is familiar with this issue and error, I would be very
grateful.
Thanks
Philip Tham
BUILD FAILED
/home/test/Automation/build.xml:2: The
following error occurred while executing this line:
jar:file:/usr/share/ant/lib/ant.jar!/org/apache/tools/ant/antlib.xml:37:
Could
not create task or type of type: componentdef.
Ant could not find the task or a class this task relies upon.
This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
- You have misspelt 'componentdef'.
Fix: check your spelling.
- The task needs an external JAR file to execute
and this is not found at the right place in the classpath.
Fix: check the documentation for dependencies.
Fix: declare the task.
- The task is an Ant optional task and the JAR file and/or libraries
implementing the functionality were not found at the time you
yourself built your installation of Ant from the Ant sources.
Fix: Look in the ANT_HOME/lib for the 'ant-' JAR corresponding to the
task and make sure it contains more than merely a
META-INF/MANIFEST.MF.
If all it contains is the manifest, then rebuild Ant with the
needed
libraries present in ${ant.home}/lib/optional/ , or alternatively,
download a pre-built release version from apache.org
- The build file was written for a later version of Ant
Fix: upgrade to at least the latest release version of Ant
- The task is not an Ant core or optional task
and needs to be declared using <taskdef>.
- You are attempting to use a task defined using
<presetdef> or <macrodef> but have spelt wrong or not
defined it at the point of use
Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath
