@Nullable and SonarQube 'Conditionally executed blocks should be reachable' warning


@Nullable and SonarQube 'Conditionally executed blocks should be reachable' warning

This might help you Apparently, this problem was caused by us using sonar-scanner without specifying sonar.java.libraries. Since it's multimodule maven project it wasn't clear to us how to specify sonar.java.libraries correctly.
Nicolas Peru, from SonarSource, suggested that we should use sonar maven plugin, instead of sonar-scanner, as the plugin has access to build classpath of the project. Indeed that solved this problem for us.

it helps some times From valgrind documentation,
How is the warning 'Source files should not have any duplicated blocks' suppressed in SonarQube?

may help you . This is a feature that is not supported : https://jira.sonarsource.com/browse/SONARJAVA-521
There is no plan to implement it for now but this might be addressed in the future.

To fix the issue you can do The solution i found to the above problem is just to comment the below options and restart the sonar server
code :
#sonar.web.host=127.0.0.1
#sonar.web.context=/sonar

like below fixes the issue libcurl links against many libraries, and some of them do not have a function like curl_global_cleanup which reverts initialization and frees all memory. This happens when libcurl is linked against NSS for TLS support, and also with libssh2 and its use of libgcrypt. GNUTLS as the TLS implementation is somewhat cleaner in this regard.
In general, this is not a problem because these secondary libraries are only used on operating systems where memory is freed on process termination, so an explicit cleanup is not needed (and would even slow down process termination). Only with certain memory debuggers, the effect of missing cleanup routines is visible, and valgrind deals with this situation by differentiating between actual leaks (memory to which no pointers are left) and memory which is still reachable at process termination (so that it could have been used again if the process had not terminated).

it should still fix some issue This code: , Imagine you call:
code :
string result = Foo<string>();
[return: MaybeNull]
public T Foo<T>()
    where T : class?
{
    return null!;
}
