How to compile xslt2-transformer.oxt LibreOffice extension

I am trying to compile the xslt2-transformer extension, because I can’t find the LibreOffice extension xslt2-transformer.oxt on the web site (if anybody has it, he is welcome).
To build from source code, I proceeded like that:
$ git clone https://github.com/dtardon/xslt2-transformer.git
$ cd xslt2-transformer/
$ make
I am getting a lot of (similar) errors during build:
mkdir -p build/classes && \
javac -d build/classes -source 1.5 -target 1.5 \
-cp "external/saxon9.jar:" com/sun/star/comp/xsltfilter/Base64.java \
com/sun/star/comp/xsltfilter/XSLTFilterOLEExtracter.java \
com/sun/star/comp/xsltfilter/XSLTransformer.java && \
touch build/javac.done

make: *** [build/javac.done] Error 1
I think my CLASSPATH is not up-to-date. I need to add the com.sun.star package and classes.
Since I am (currently) on OSX, my LibreOffice is installed on /Applications/LibreOffice.app and I found some classes in ./Contents/Resources/java.
So I update the CLASSPATH that way:
export CLASSPATH=/Applications/LibreOffice.app/Contents/Resources/java:$CLASSPATH
But, I have the same errors. How can I fix that?
EDIT 1 put some jar in the CLASSPATH
I tried that:
$ export CLASSPATH=/Applications/LibreOffice.app/Contents//Resources/java/ridl.jar:.
I have less errors.
EDIT 2 The build succeed!
I finally added the following jar files to the CLASSPATH:
/Applications/LibreOffice.app/Contents//Resources/java/ridl.jar
/Applications/LibreOffice.app/Contents//Resources/java/jurt.jar
/Applications/LibreOffice.app/Contents//Resources/java/juh.jar
/Applications/LibreOffice.app/Contents//Resources/java/unoil.jar
And I get the extension!

Finally, to build from source code, I proceeded like that:
git clone https://github.com/dtardon/xslt2-transformer.git
cd xslt2-transformer/
export CLASSPATH=/Applications/LibreOffice.app/Contents/Resources/java/ridl.jar:\
/Applications/LibreOffice.app/Contents/Resources/java/jurt.jar:\
/Applications/LibreOffice.app/Contents/Resources/java/juh.jar:\
/Applications/LibreOffice.app/Contents/Resources/java/unoil.jar
make
The result is build/xslt2-transformer.oxt.

Using UMLGraph to generate single dot file for multiple java classes

How can I ask UMLGraph to generate a single diagram for all the underlying .java classes within a package ?
I am using UMLGraph along with Graphviz to generate a .png UML diagram file.
The command that I am running to geenrate a.dot file is :
java -jar C:/Program Files/Java/jdk1.7.0_80/lib/UmlGraph.jar -all -private A.java
This runs succesfully to geenrate a .dot file.
However,I wish to create a single UML diagram out of them ( They are all linked to eachother via java code).
The "uml-parser-test-1" (folder/package) contains all about 5 .java files and for that I am running
C:/Users/xyz > java -jar "C:/Program Files/Java/jdk1.8.0_60/lib/UmlGraph.jar" -all -private "D:/xyz/abcd/uml-parser-test-1/"
When I run above code , I get an error : UMLGRAPH ERROR - ILLEGAL PACKAGE NAME
Where am I going wrong
**EDIT:: 6th Oct**
There was an issue with umlgraph.jar path and I had corrected it. Thanks for pointing that out.
Now I am able to run the command you suggested without any errors. THe thing is my "Persons" package(folder) contains 4 java files(A,B,C,D.java). When I run the command, it generated .dot file on the command line and not in my file system.Moreover, it is incomplete as there is no information about classes :
Below is the trace of my command line .

Any idea, why it is not parsing the class details?

You must specify in the command line invocation the package name and the directory where its source code is located. The following example, when run in the UMLGraph directory, generates a diagram for the UMLGraph classes.
java -classpath "lib/UmlGraph.jar;C:\Program Files\Java\jdk1.8.0_20/lib/tools.jar" org.umlgraph.doclet.UmlGraph -package -output - -sourcepath src/main/java org.umlgraph.doclet | dot -Tpng -oumlgraph.png

GnuPG for Java library ant build issue/bug

I'm working GnuPG Java API to encrypt/decrypt files.
Googled and found a Java Wrapper GnuPG for Java, Java wrapper for GPGME(GnuPG Made Easy,C language library).
Official website also referring this as the Java wrapper.
So followed the instructions, set up ant and tried to run ant clean release
it is throwing errors.
But maven build working and jar file also generated.
Following error occured while running ant.

Can anyone help me to solve this issue ?
Where I'm making mistake ?

I rewrote my answer because I wanted to create a complete guide.
Install GnuPG and MinGW-Get to a directory without spaces.
After you installed MinGW with !!!GUI!!!, open mingw-get, install these components:
mingw32-gcc (check all)
mingw32-libz (the dll is the most important)
Download and install MSYS, that is a command line toolkit for running commands like make.
Then put c:\msys\1.0\bin\ (or wherever you installed it) on the beginning of the PATH variable. Restart eclipse or open a new cmd, and it should work.
In the build.xml:
line 21:
classpath="lib/junit-4.4.jar" added.(and the junit is in the lib dir)
In the GNUmakefile:
line 9 :
ALL_CFLAGS := -Wall -Wno-deprecated-declarations -fPIC
line 10:
ALL_CPPFLAGS = -D_REENTRANT -D_THREAD_SAFE -D_FILE_OFFSET_BITS=64 -DLARGEFILE_SOURCE=1 \
-I"c:/WORK/x/gnu/jdk/jdk1.8.0_25/include" -I"c:/WORK/x/gnu/jdk/jdk1.8.0_25/include/win32"
line 21-27:
JAVA_HOME := c:/WORK/x/gnu/jdk/jdk1.8.0_25
ALL_CFLAGS += -mms-bitfields -Wl,--add-stdcall-alias
ALL_CPPFLAGS += -I"c:/WORK/x/gnu/jdk/jdk1.8.0_25/include/win32" -I"c:/WORK/x/gnu/jdk/jdk1.8.0_25/include" -I"c:/GNU/GnuPG/include"
ALL_LDFLAGS := -s -shared -Wl,--enable-auto-import
ALL_LIBS := -L"c:/GNU/GnuPG" -lgpgme-11
GNUPG_LIB := $(BUILD_DIR)/gnupg-for-java.dll
line 63:
$(CC) $(DEBUG) $(ALL_CFLAGS) $(ALL_LDFLAGS) $^ -o "$(BUILD_DIR)/gnupg-for-java.dll" $(ALL_LIBS)
Summary: This is working for me and outputs the jar and dll file to the build directory. My work directory was c:/WORK/x so replace the paths where it is different. Don't use "Program Files" anywhere, as you can see I had to copy everything from there.

The error message is telling that it cannot find mingw32-gcc in /bin/sh.
You should install mingw at first and add it to your path. Check that mingw32-gcc can be launched from the command line.
Are you running the ant script from cygwin? It's a bit strange that it is referring /bin/sh. Maybe you should try to run it from cygwin. Or check the build.xml file to see how mingw32-gcc is called. It must be recompile-c-code target.

Android NDK: Eclipse parameter and javah

I spent hours and hours on it not moving an inch forward. I have redone the project several times and nothing else is left outside places. Hope someone here can shed some light pointing out some direction.
On Linux Eclipse IDE panel > Run > External Tools > External Tools Configurations:
Name: Dev javah
Tab [main]:
* location: /usr/java/jdk1.6.0_25/bin/javah
* working directory: ${workspace_loc:/Dev/bin}
* Arguments: ??
I have tried:
* Arguments: -d ${workspace_loc:/Dev/jni} com.dev.DevActivity ${project_classpath:Dev} com.pkgpub.DevActivity
which gives me:
1 error
javadoc: error - Illegal package name: "/home/user/dev/Dev/bin/classes"
and also tried:
* Arguments: -d ${workspace_loc:/Dev/jni} com.dev.DevActivity
That gives...
error: cannot access com.dev.DevActivity
class file for com.dev.DevActivity not found
javadoc: error - Class com.dev.DevActivity not found.
Error: No classes were specified on the command line. Try -help.
similarly to -
* Arguments: -d ${workspace_loc:/Dev/jni} com.pkgpub.DevActivity
That gives me:
error: cannot access com.pkgpub.DevActivity
class file for com.pkgpub.DevActivity not found
javadoc: error - Class com.pkgpub.DevActivity not found.
Error: No classes were specified on the command line. Try -help.
But when I run:
which javah
/usr/bin/which: no javah in (/usr/lib64/qt-3.3/bin:/usr/lib64/ccache:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/user/android-sdks/tools:/home/user/android-sdks/platform-tools:/opt/android/android-ndk-r7:/home/user/.local/bin:/home/user/bin:/home/user/android-sdks/tools:/home/user/android-sdks/platform-tools:/opt/android/android-ndk-r7:/home/user/android-sdks/tools:/home/user/android-sdks/platform-tools:/opt/android/android-ndk-r7)
The question is... the project is not compiling because javah is not visible to Eclipse NDK, or due to parameter details that something is missing? And in such case, how to get it fixed?
Thanks.

try adding
-classpath bin/classes
as parameter to javah

Specially for Android:
use classes right after bin like project_location/bin/classes, this worked for me on Linux Fedora
javah -d /var/www/project/jni/ -classpath /var/www/project/bin/classes/ com.android.TestClass

#BlackBelt - thanks man for your suggestion!
Here is the parameter that worked, solving the javah side for the compiling process:
-d ${workspace_loc:/Dev/jni} com.pkgpub.Dev -classpath ${workspace_loc:/Dev/bin/classes/} com.pkgpub.Dev
Where pkgpub is the package name, and Dev is the project name. It is worth to mention that the project has the files: \src\Dev.java; \jni\Dev.c; \jni\Dev.h; \bin...\pkgpub\Dev.class.
Now it generates the file jni/com_pkgpub_Dev.h with the right content. Which is great!
However the ndk-build is still not completely linking, and does not generate the com_pkgpub_Dev.c file. So, from Project > Project Build - comes the message:
**** Build of configuration Build (GNU) for project Dev ****
ndk-build
make: *** No rule to make target `jni/com_pkgpub_Dev.c', needed by `obj/local/armeabi/objs/dev/com_pkgpub_Dev.o'. Stop.
**** Build Finished ****
From this message it sounds like some parameter should be missing from the file /jni/Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_CFLAGS := -DHAVE_INTTYPES_H
LOCAL_MODULE := dev
LOCAL_SRC_FILES := com_pkgpub_Dev.c Dev.c
include $(BUILD_SHARED_LIBRARY)
To solve it, it is just necessary to create the missing file "jni/com_pkgpub_Dev.c". This file content should be manually made based on the automatic generated code contained in the file "jni/com_pkgpub_Dev.h".
Now, it works!

Why can't I load this class file in Rhino console?

I'm prototyping a web page scraper using Rhino and Env-js. Nevermind that the documentation for both projects is atrocious... I'm trying to load up the File.java example class that is supplied with Rhino. For simplicity sake, I've got File.java, js.jar, jline.jar and env.rhino.1.2.js all in one directory. I've tried specifying the current directory using the classpath command line option, but still whenever I call defineClass("File") I get an error saying the class file isn't found. What am I doing wrong here??
$ ls -1
File.java
env.rhino.1.2.js
jline.jar
js.jar
$ java -cp .:js.jar:jline.jar jline.ConsoleRunner org.mozilla.javascript.tools.shell.Main -opt -1
Rhino 1.7 release 2 2009 03 22
js> defineClass("File")
js: "<stdin>", line 2: Class "File" not found.
at <stdin>:2

Don't you need to compile File.java before using it, as the classpath "." only makes sense if it contains some compiled class in it?
