I'm trying to run the latex plugin to create pdf via pdflatex.
The following is the pom snippet to configure the plugin:
{code}
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>latex-maven-plugin</artifactId>
<version>1.1</version>
<executions>
<execution>
<phase>pre-site</phase>
<goals>
<goal>latex</goal>
</goals>
<configuration>
<binariesPath>/usr/bin/pdflatex</binariesPath>
<docsRoot>${project.build.directory}/generated-site/latex/maui-guide/maui-guide.tex</docsRoot>
<latexBuildDir>${project.build.directory}/generated-site/latex/maui-guide/</latexBuildDir>
</configuration>
</execution>
</executions>
</plugin>
{code}
which results into the following error message if i do a mvn clean site (-X
option)
{code}
