Answer 1

Maybe you incorrectly set the git executable path.

It shouldn't be C:\Program Files\Git, but C:\Program Files\Git\bin\git.exe
(this is similar to JENKINS-6181)

The Git plugin page does mention:

If you are seeing output indicating Git could not clone, something like the output below, go to to the Jenkins configuration settings (not the project settings, the global ones) and change the Git path to a fully qualified path (eg. not "git" but "/usr/bin/git" or wherever your Git binary is installed).

In your case, check that C:\Program Files\Git is indeed your Git installation path.

Answer 2

In your logs, looks like Jenkins agent doesn't have enough permissions to execute Git

hudson.model.AbstractBuild$AbstractBuildExecution.defaultCheckout(AbstractBuild.java:651)
        at jenkins.scm.SCMCheckoutStrategy.checkout(SCMCheckoutStrategy.java:88)
    Caused by: java.io.IOException: Cannot run program "C:\Program Files\Git" (in directory "E:\sw\jenkins\workspace\se12"): CreateProcess error=5, Access is denied

Detail to

CreateProcess error=5, Access is denied

For me the issue was different, it was

CreateProcess error=2, The system cannot find the file specified

Doing some research I came across this issue https://issues.jenkins.io/browse/JENKINS-12353

At the very bottom one guys says that the default PATH configuration in windows points to

C:\Program Files\Git\cmd

When it should be

C:\Program Files\Git\bin

As I have jenkins agents in remote machines, I had to restart my agents to reload the PATH change in the host.
