## How do I get rid of issues that are False-Positives?
**False-Positive and Won't Fix**  
You can mark individual issues False Positive or Won't Fix through the issues interface. If you're using PR analysis provided by the Developer Edition, issues marked False Positive or Won't Fix will retain that status after merge. This is the preferred approach.

**//NOSONAR**  
For most languages, SonarQube supports the use of the generic mechanism: `//NOSONAR` at the end of the line of the issue. This will suppress all issues - now and in the future - that might be raised on the line.

## How do I find and remove projects that haven't been analyzed in a while?
In **[Administration > Projects > Management](/#sonarqube-admin#/admin/projects_management)** you can search for **Last analysis before** to filter projects not analyzed since a specific date, and then use bulk **Delete** to remove the projects that match your filter.

This can be automated by using the corresponding Web API: `api/projects/bulk_delete?analyzedBefore=YYYY-MM-DD`.

## How do I trigger a full ElasticSearch reindex?
Currently, the only way to force a reindex is to:

* Stop your server
* Remove the contents of the $SQ_HOME/data/es7 directory
* Start your server

Before doing this, you should be aware first that processes are in place on the SonarQube side that out-of-sync indices are detected and corrected, and second that a full re-index can be quite lengthy depending on the size of your instance.

## Why can't I use my HTTP Proxy since I upgraded to Java8u111?

If you are getting this error in the logs when trying to use the Marketplace:
```
java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 Proxy Authentication Required
```
... you probably upgraded your Java8 installation with an update greater than 111. To fix that, update _$SONARQUBE_HOME/conf/sonar.properties` like this:
```
sonar.web.javaOpts=-Xmx512m -Xms128m -XX:+HeapDumpOnOutOfMemoryError -Djdk.http.auth.tunneling.disabledSchemes=""
```
