-------------------------------
Resolution: Not A Bug
Assignee: Lukas Theussl
This is not a bug but a documented 'feature' of Velocity, see
http://velocity.apache.org/engine/devel/user-guide.html#escapinginvalidvtlreferences
> APT doesn't support specific code snippets embedded inside XML as verbatim
> text
> -------------------------------------------------------------------------------
>
> Key: DOXIA-447
> URL: https://jira.codehaus.org/browse/DOXIA-447
> Project: Maven Doxia
> Issue Type: Bug
> Components: Module - Apt
> Reporter: Parameswaran Raman
> Assignee: Lukas Theussl
> Priority: Blocker
> Attachments: test.apt.vm
>
>
> As part of compiling documentation for our project Oozie, we require adding
> XML snippets with expressions of a particular kind such as:
> ${wf:errorCode('wordcount')}. These expressions are known as EL functions and
> they would appear at numerous places in the documentation. Unfortunately,
> Doxia APT compiler is not able to parse these expressions and throws an
> exception.
> Following is the XML snippet desired (to be placed inside verbatim tag):
> --------------------------------------------------------------------------------------------
>
> <configuration>
> <property>
> <name>mapred.job.queue.name</name>
> <value>${queueName}</value>
> </property>
> <property>
> <name>error.message</name>
> <value>Something went wrong: ${wf:errorCode('wordcount')}</value>
> </property>
> </configuration>
> --------------------------------------------------------------------------------------------
>
> On trying to build the maven project for the site documentation,
> $ mvn site
> I get the following error:
> --------------------------
> [ERROR] org.apache.velocity.runtime.parser.ParseException: Encountered
> ":errorCode(\'wordcount\')}</message>\n </kill/>\n <end
> name=\'end\'/>\n</workflow-app>\n----------------------------------------------------------------------------------\n\n
> <<Notes:>>\n\n <<" at line 134, column 44.
> Was expecting one of:
> "}" ...
> <DOT> ...
> Observations:
> -------------
> 1) It appears that whenever I use any text of the format:
> ${wf:errorCode('wordcount')} , APT throws a parse exception (even if its
> contained in the verbatim block).
> 2) I tried escaping the characters - {, $, :, etc.. but it doesnt work
> either.
> 3) In general we tried the following patterns and found that:
> ${foo} works
> ${foo()} fails
> ${foo:bar} fails
> ${foo:bar()} fails
> We found a workaround (that solves this issue partially), however we would
> need this bug to be fixed as early as possible as it is a critical blocker in
> our documentation process.
> Workaround (based on response from the maven nabble forum):

> I have attached a sample source file (test.apt.vm) that you can use to
