When trying to generate JavaDoc in Android Studio, it acts up and shows countless errors concerning non-existing packages and unknown symbols (mostly Android-related stuff).
Finally I get this error message:

Check your installed Kotlin plugin in the idea(Tools>Kotlin>Configure Kotlin Plugin Updates). Must be same as in your build.gradle file.
There's an IntelliJ / Android Studio plugin that's made just for the Kotlin Serialization support, separate from the main Kotlin plugin. From the Working in IntelliJ IDEA section of the readme:
Because serialization is still highly experimental, it is shipped as a separate artifact from "big" Kotlin IDEA plugin. You can download additional IDEA plugin for working with projects that uses serialization from its TeamCity build page
It provides links to the latest TeamCity builds for this plugin, including this one for Kotlin 1.2.40.
Since they only currently publish this plugin through TeamCity, you would have to install it manually by going to Preferences > Plugins > Install plugin from disk...
For anyone using IntelliJ instead of Android Studio, if the plugin doesn't solve the problem, the same readme says to:
try to use gradle for running builds: Settings - Build, Execution, Deployment - Build Tools - Gradle - Runner - tick Delegate IDE build/run actions to gradle; or launch builds from console.
There's an open ticket on Github about this error message, and it might also be worth keeping an eye on that.
So I'm just exporting a basic program with one library tornadofx-1.7.11.jar plus the standard Kotlin library. I've exported it fully using this guide. I tried running it in the command line, but received this error:

I've looked up my issue here, and it said that my error has to do with a broken class path. I have no idea what I'm doing with regards to class paths, but the guide mentioned earlier stated to just put the names of all jars. If you really want it, here's my class path: tornadofx-1.7.11.jar. Just that one line. I'm not sure if I should add more, but I did it like the example showed.
If needed, I'm running on Intellij IDEA version 2017.2.6.IC-172.4574.11.
You need to add the kotlin stdlib to the classpath to to run it from the command line.
Something like:
java --class-path tornadofx-1.7.11.jar stdlib.jar -jar myprogram.jar
Running it from InteliJ is simpler since it configures it on its own.

With or without the previous step, I added com.microsoft.z3.jar to Classpath, located at the Plugin.xml Runtime tab. In this case, the plugin is not finding the handler that is invoked after button press command.

In fact, this approach worked for me a previous a installation (Dell, Intel, x64, Eclipse Mars (x64), Java 1.8 x64)!
Following the discussion in https://github.com/Z3Prover/z3/issues/1093, I configured Native Library Location of com.microsoft.z3.jar with the Z3 Build directory. Calling the Z3 Build from Eclipse plugin, the error reported is the same as in Approach 2, but calling it from a Java application, the error is more specific:

What is working is when you have a Java application under the Z3 build directory. Can anyone help how to use the Z3 build directory from a Java application, or from Eclipse plugin. By the way, I followed approach #2, was working fine until I try to replicate it (because my laptop crashed) and forced to use another laptop, then the same procedure is not working for me (I had luck, before). Right now, the new laptop has the following settings:

I really appreciate for your help in advance.

At runtime your code needs to find com.microsoft.z3.jar, libz3.dll/.so/.dylib, and libz3java.dll/.so/.dylib. Java takes care of the first one, but the operating system will have to find the other libraries, i.e., whatever environment your code runs in must be set up such that PATH (Windows), LD_LIBRARY_PATH (Linux), or DYLD_LIBRARY_PATH (OSX) point to the libraries. Also, make sure that your version of Z3 and your version of Java are both 32-bit or 64-bit, otherwise the error messages you get may not be very informative.
For some flavors of Java, it may also be necessary or helpful to provide the java.library.path setting to the JVM.
I have installed PIT Mutation testing Idea plugin for IntelliJ. I have a small demo project in Java 8, it runs the mutation tests perfectly.
Our larger project, which is still Java 7 consists of a parent with a lot of Maven modules. I'm not sure if the problem lies in the modules or in some other dependency problem, but when I run the plugin on this project it fails with the following error. Google hasn't been very helpful except I'm not the only one, so I was hoping anyone on SO has run into the problem and knows how to fix it.
The error I get after the build (when mutation test should start running) is:
Exception in thread "main" java.lang.NoSuchMethodError: joptsimple.OptionParser.acceptsAll(Ljava/util/List;Ljava/lang/String;)Ljoptsimple/OptionSpecBuilder;

Kindly help me with the solution
There are several issues that can prevent this functionality to work.
The root cause is that Pentaho uses SWT functionality that requires one of two browsers that installed in the operating system. Refer to this faq (http://www.eclipse.org/swt/faq.php#browserlinux).
In my case, we must choose whether we want to use WebKitGTK (webkit) or Mozilla Firefox (mozilla) by adding a VM option to the java command line :
-Dorg.eclipse.swt.browser.DefaultType=mozilla
In my system, Ubuntu 14.04, the webkit browser causes an error in libsoup, so I need to set this to mozilla. For reference see https://bugs.launchpad.net/ubuntu-gnome/+bug/1163501 for libsoup error in Eclipse which also uses SWT, similar to Pentaho.
Then, we need mozilla firefox to be present in the system, and also the mozilla XUL runner library. Install firefox first :
apt-get install firefox
Install XUL runner 1.9.2 because 2.0.0 or later is said to be incompatible (see http://jira.pentaho.com/browse/PDI-8730).
wget http://ftp.mozilla.org/pub/mozilla.org/xulrunner/nightly/2012/03/2012-03-02-03-32-11-mozilla-1.9.2/xulrunner-1.9.2.28pre.en-US.linux-x86_64.tar.bz2
tar -xjf xulrunner-1.9.2.28pre.en-US.linux-x86_64.tar.bz2
mv xulrunner /opt/xulrunner-1.9.2
Configure the xulrunner path using this VM option :
-Dorg.eclipse.swt.browser.XULRunnerPath=/opt/xulrunner-1.9.2
We also need to configure LD_LIBRARY_PATH and MOZILLA_FIVE_HOME to point to the xulrunner :
MOZILLA_FIVE_HOME=/opt/xulrunner-1.9.2
LD_LIBRARY_PATH=${MOZILLA_FIVE_HOME}:${LD_LIBRARY_PATH}
The final setting in spoon.sh is :
(spoon.sh, about line 13)
MOZILLA_FIVE_HOME=/opt/xulrunner-1.9.2
LD_LIBRARY_PATH=${MOZILLA_FIVE_HOME}:${LD_LIBRARY_PATH}
(spoon.sh, about line 184)
if [ -z "$PENTAHO_DI_JAVA_OPTIONS" ]; then
PENTAHO_DI_JAVA_OPTIONS="-Xmx512m -XX:MaxPermSize=256m -Dorg.eclipse.swt.browser.DefaultType=mozilla -Dorg.eclipse.swt.browser.XULRunnerPath=/opt/xulrunner-1.9.2"
fi
You can also fix this issue by replacing the SWT jar and SWT-GTK jar in Kettle's libswt folder.
Diethard Steiner described the simple process on his blog, using the JAR files from Eclipse:
http://diethardsteiner.github.io/pdi/2015/06/07/Fixing-PDI-GLib-CRITICAL.html
This way you don't have to mess with start script; but keep in mind that the change will be overwritten by an update, too.
