I have tried latest Eclipse(2019-12) and installed CRS 12.13.0.GA without issues.
Which Eclipse version have you tried?
It looks like like you are trying to install quite old version of CRS.

PS: You can use JIRA for reporting issues with CRS: https://issues.redhat.com/projects/JBDS/ or witj JBoss Tools https://issues.redhat.com/projects/JBIDE/
I have problem launching STS application. I have downloaded Win 64 bit that matches my system and I have jdk 1.8 installed. That is the only version I have.
I am getting the following error when I launch STS
"version 1.7.0_67 of the JVM is not suitable for this product. Version:1.8 or greater is required"
The only reason why your STS is not working is either because you don't have JAVA properly installed or because your STS version(32bit/64bit) is not compatible with your windows.
Make sure both of these things are fixed.
Trying a POC, followed as suggest at https://dzone.com/articles/running-apache-kafka-on-windows-os also a reference is there Is there an easy way to install Kafka on Windows?. I was able to run zookeeper 3.4.9 but not kafka 2.11-0.10.2.0, when i try to start i see
Exception in thread "main" java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=kafka/Kafka, offset=6 i have IBM JDK 1.7.0 installed on windows 7 64-bit version. Any suggestions please to resolve this issue?
It may be because you are trying to run Kafka build on a different Java runtime version than it was compiled.
For Kafka 0.10.2.0, you will have to upgrade your java version to JDK 1.8 or if you want to stay in JDK 1.7, make sure you are on u51 or newer.
For further reference on above, check the following link,
https://kafka.apache.org/documentation/#java
Update your jdk 1.7 to jdk 1.8
I have a installer which is built with install4j 5.1.2. When i try to install it on Mac OS X 10.7.4. It complains saying
"No JVM could be found on you
system.
Please define EXE4J_JAVA_HOME
to point to an installed JDK or JRE or download a JRE from
www.java.com"
Then i download just the JRE1.7_07 from Oracle and tried again, i got the same error. Where as if i install full JDK1.7_07, then everything works fine.
Additional Information:
If i use Apple JRE 1.6 installer works fine. But my app needs JRE 1.7.
I also defined environment variables for JAVA_HOME, EXE4J_JAVA_HOME when i installed JRE1.7, Still i saw the same error. I have a feeling that, install4J is not reading the JRE when JRE is installed.
If i install JDK, then the JRE is in the following location
/Library/Java/JavaVirtualMachine/
where as if i install only JRE, it is in the following location
/Library/Internet Plug-ins/JavaAppletPlugin.plugin
I am not sure, if i am missing something. any pointers on how to resolve this particular issue is very helpful.
I got below email from install4j support.
Hi,
Thanks for your email. Indeed, 5.1.2 cannot find the JRE but only the JDK, since
the JRE was not released when OpenJDK support was implemented for install4j. This
is implemented in the current 5.1.3 build:
http://download.ej-technologies.com/beta/install4j_windows_5_1_3.exe
http://download.ej-technologies.com/beta/install4j_windows-x64_5_1_3.exe
It will be released at the end of the month.
Kind regards,
