Gradle version :
Gradle 1.12
Build time: 2014-04-29 09:24:31 UTC
Build number: none
Revision: a831fa866d46cbee94e61a09af15f9dd95987421
Groovy: 1.8.6
Ant: Apache Ant(TM) version 1.9.3 compiled on December 23 2013
Ivy: 2.2.0
JVM: 1.7.0_45 (Oracle Corporation 24.45-b08)
OS: Windows 7 6.1 x86
Jdk is 1.7.45.
Is there any help? I tried stopping the anti virus assuming the connection are getting terminated by AV. However, the issue re-occurred when the AV was turned off.

I assume this is a problem where Gradle cannot connect to the gradle Daemon. Your machine probably has an issue with its networking config, which needs to be worked out.
A possible workaround would be to run without the Daemon, using the --no-daemon option. If that still doesn't work, there is some other reason why it tries to establish a connection, probably due to a custom plugin or build script.

I was using JDK v1.7.0_45 and I now use 1.7.0_79. Ever since the upgrade I am not observing this issue. I switched back to v1.7.0_45 this morning and I am already noticed "Unable to establish loopback connection" twice out of six iterations.

but when i update to JDBC 4.2 Driver, 42.2.1 work well.
Maybe someone from sonarqube see and fix it.
Indeed the version of PostgreSQL driver packaged in SonarQube 6.7.1 has some bugs. Driver is upgraded in SonarQube 6.7.2, not released at the time of writing.

I was wondering whether I missed any setup procedures. The getting started guide says it should running out of the box. I am using OSX Yosemite 10.10.5
Thanks in advance.
It appears this is a JDK bug and it looks like this could be fixed by updating your JDK, what version are you currently on?
It looks like CASSANDRA-8220 (C* 2.2.1+, and 3.0.0-alpha1) was introduced to work around the problem, but I think upgrading your JDK should fix this as well.

RuntimeMBeanCallable.call() exception

When a .wlapp file is deployed in MobileFirst Console, we get the following error in the logs. This happened after we upgraded MobileFirst Server from 6.3 to 7, but don't know if this is related to the version of MobileFirst.

MobileFirst version 7
WAS server version 8.5.5.5
JRE version 1.6
Re-deploying the MobileFirst artifacts to the application server should normally not be required as inspecting the logs and configuration usually will lead to the root cause of the problem. However in some cases starting over to get things right will work.
As mentioned in the comments, re-deployment of the server artifacts nullified the issue that was experienced.

Sonar Runner not starting

I am trying to configure Sonar 3.2 in my Windows 7 64 bit operating system with java 1.7.0_05.
When I start Sonar runner - 1.4, I am getting this exception

any solution to solve this issue is appreciated.
I am able to download hibernate-entitymanager-3.4.0.GA.jar from http://localhost:9000/batch/hibernate-entitymanager-3.4.0.GA.jar in the browser.
I see in your configuration details that you are running Sonar using a Java 7 VM: could you please try with Java 6?
That might not be the root cause, but I know we have users who reported some issues with Java 7.
This is the error I get when I execute the runner without administrative privileges.
If you're launching the runner from a DOS prompt, try right-clicking on "Windows Command Processor" and choosing "Run as Administrator."

Starting of Tomcat failed in Netbeans 7

I am trying to run my application via Netbeans 7.0 on tomcat 7.0.11 (bundled with the Netbeans itself).
When I try to run the application I am getting the following error.
I have reinstalled everything many times but I am still getting same issues.
It runs properly first time and then if I stop the server and then try to start it again then it creates the problem. At times when I restart my PC it works and sometimes even restarting the PC does not work.
Below is the error stack from Netbeans 7.0

Please help !
I'd recommend looking at the the Tomcat logs to find out what the specific error is.
