Unable to package Meka 1.9.2 or Snapshot

[gb-git]

I have tried to package Meka 1.9.2 with no success.

I am following the command in the tutorial: mvn clean install

And I get the following stack trace:

[INFO] --- latex-maven-plugin:1.4.1:latex (default) @ meka ---

I expect the project to compile and provide me with an environment with the BAT file, lib directory with needed dependencies and successfully built meka-X.X.X.jar file.

I am using Windows 8.1. Pro on an Intel P7 computer with 16GB of RAM. I am compiling with Java Oracle JDK 1.8.0_181 under cygwin (I have built many other projects with success, so I do not think the problem is in my cygwin setup).

Note that I also tried with Meka snapshot (Latest commit fe5eeb5) with no success.

Any help would be greatly appreciated.

You don't seem to have pdflatex on your system PATH. This executable is used to turn the LaTeX documentation into PDFs. On my Linux Mint 18.2, I use texlive (http://tug.org/texlive/), but you should be able to use MikTeX on Windows as well (https://miktex.org/). Once you have installed your LaTeX distribution, make sure that the pdflatex is accessible via the PATH environment variable.

Thank you fracpete. I installed miktex-2.9.6850 and configured the path as suggested. When I tried to build again (mvn clean install), It processed several files with pdflatex.exe, but failed with the following error:

! LaTeX Error: File `epsf.sty' not found.

I found a different way to get it to work:

Need to add this plugin to get the JARs in local directory.

<plugin> 
<groupId>org.apache.maven.plugins</groupId> 
<artifactId>maven-dependency-plugin</artifactId> 
<configuration> 
<outputDirectory> ${project.build.directory} </outputDirectory> 
</configuration> 
</plugin>

Then run

• mvn clean install -DskipTests
• mvn dependency:copy-dependencies
• Move ./target/dependency directory to ./lib
• Copy ./target/meka-1.9.2.jar to ./lib
• Added run.bat file

  @ECHO OFF
  SET MEMORY=512m
  SET MAIN=meka.gui.guichooser.GUIChooser
  java -Xmx%MEMORY% -cp ".\lib\*" %MAIN% %1

Then execute the run.bat file which launches Meka. I hope this workaround is useful for someone else.

The reason that pdflatex fails is that you are missing (at least) one LaTex package: epsf (https://miktex.org/packages/epsf)

Also, to turn off the LaTeX generation, try using this flag on the commandline: -Dlatex.dummyBuild=true

Thank you!
