Not able to install the Sikulix setup 1.1.3 jar in Linux - sikuli-x

Url to download the Sikulix setup 1.1.3 jar : https://launchpad.net/sikuli/+download
Command used to install Sikulix setup 1.1.3 jar -->java -jar Sikulix setup 1.1.3 jar
While installing sikulix setup 1.1.3 jar, i am getting the error as 'Something serious happened! Sikuli Not Usable'... Check the error log

First of all there is new version 2.x of Sikuli that works on latest Linux OS. Old 1.1.3 is not supported anymore
However the answer your question: you need manually to install Java opencv library in older Sikuli versions. Note this will work on Ubuntu 16 and 14.

3.6.0 version is latest version to download.
Someone was saying there is maven 4 is latest. Not sure where to download this from and can we use this for java 8.
Which one is latest version to use?
From https://maven.apache.org/download.cgi
Apache Maven 3.6.0 is the latest release and recommended version for
all users.
Works nicely with Java 8. Note that your IDE may bundle an older version in the unlikely case you run into problems.

How to Install an Earlier Version of libsvn-java

I installed the latest version of Eclipse Neon in Ubuntu 16.04.1 LTS. When I attempted to create a PHP project I got this error:
Failed to load JavaHL Library.
These are the errors that were encountered:
no libsvnjavahl-1 in java.library.path
no svnjavahl-1 in java.library.path
no svnjavahl in java.library.path
java.library.path = /usr/java/packages/lib/amd64:/usr/lib/x86_64-linux-gnu/jni:/lib/x86_64-linux-gnu:/usr/lib/x86_64-linux-gnu:/usr/lib/jni:/lib:/usr/lib
So I attempted to install JavaHL follow the instructions at:
http://subclipse.tigris.org/wiki/JavaHL
In Eclipse: Help => Installation Details I see I have Subclipse version 1.10.13. According that web page I need to install SVN/JavaHL version 1.8.x. When I follow the directions farther down that page and execute the command:
sudo apt-get install libsvn-java
what is installed is version 1.9.3-2ubuntu1. How can I install version 1.8.x?
I attempted to install Subclipse version 1.12.x by pasting the URL: http://subclipse.tigris.org/update_1.12.x
In Eclipse: Help => Install New Software => Work with field, after removing both Subclipse and SVNKit. But the versions it was going to install was still Subclipse 1.10.13 and SVNKit Library 1.8.12
You are doing the right thing. The Subclipse version is the same because it is not possible to host both the 1.8.x and 1.9.x version of the JavaHL plugin on the same site and there is otherwise no difference in the versions.
That said, since you have 1.9.x available you should just move on to the new location and version of Subclipse that only supports 1.9.x. The project has moved here:
https://github.com/subclipse/subclipse
Information on installation and JavaHL is in the wiki.
Note that other than a few small bug fixes that have been released, it is not much different than the version that was on tigris. That said, that version is dead and will not receive any more updates so it makes sense to move to this version now.

Is there a way to build JRuby jars for lower Java versions on mac?

I am playing around with JRuby with mac, and have installed 1.7 JDK, and created a jar file to see how it would go on other macs, but since the current Mac's default Java is 1.6, the jars could not be opened.
I tried to install 1.6 JDK, but couldn't find a mac version for it, is it possible to build for Java 1.6, or am I doing something wrong?

Eclipse setup for Hadoop development

I am using hadoop 1.0.3 version .
I tried configuring hadoop Eclipse Indigo.
But It failed to start dfs and showed error failed to login.
plz suggest me what is the problem in map/reduce?
edit : I am using windows 7 so firstly install cygwin than hadoop1.0.4 and started service on
http://127.0.0.1:50030/ and http://localhost:50070/ successfully.
Check if you install hadoop properly. Try to install hadoop plugin, as you can see in install plugin. You can see a tutorial for this in haddop video tutorial. Also, take a look to eclipse setup for hadoop development.
Eclipse Indigo is version 3.7. You can read "Any eclipse before 3.6 is compatible to the eclipse plugin. (Doesn't work with Eclipse 3.7)" http://www.orzota.com/eclipse-setup-for-hadoop-development/

Problems installing the heroku eclipse plugin

I get this error
Cannot complete the install because one or more required items could not be found. Software being installed: Heroku Eclipse Plugin 1.0.0 (com.heroku.eclipse.feature.feature.group 1.0.0) Missing requirement: Heroku Eclipse Plugin 1.0.0 (com.heroku.eclipse.feature.feature.group 1.0.0) requires 'org.eclipse.m2e.feature.feature.group 1.0.100' but it could not be found
I have eclipse Juno.
Let me know if I can support you with any other info to help resolve this issue.
I have Ubuntu 12.04LTS
I got this same error message. Disabling my McAfee and then restarting fixed the problem for me. I'm thinking it was a firewall issue.
I had the similar problem. Please check your eclipse version. Heroku says it needs,
Eclipse v 3.7 or higher (Java or Java EE edition)
The following version works for me, Indigo (v 3.7)
This (org.eclipse.m2e.feature.feature.group 1.0.100) is referring to a plugin that is missing - the Maven Integration for Eclipse. Search the Eclipse Marketplace for that plugin. Once it's installed, try installing the Heroku plugin again. This worked for me on Indigo. It's weird that this isn't listed as a requirement.
