 This permission grants access to parts of the Jenkins system configuration.
 Only features that won't have an impact on Jenkins' overall security and stability should have their permission requirement lowered from ADMINISTER to MANAGE. For example, many scripting and code execution features (e.g., configuring master agents, paths to tools on master, etc.) are unsafe to make available to users with only this permission, as they could be used to bypass permission enforcement and elevate permissions.
 
 This permission is disabled by default and support for it considered experimental. Administrators can set the system property jenkins.security.ManagePermission to enable it.

 - getInstanceOrNull
```
@CLIResolver
 @CheckForNull
public static Jenkins getInstanceOrNull()
```
 Gets the Jenkins singleton. get() is what you normally want.
 In certain rare cases you may have code that is intended to run before Jenkins starts or while Jenkins is being shut down. For those rare cases use this method.
 In other cases you may have code that might end up running on a remote JVM and not on the Jenkins master. For those cases you really should rewrite your code so that when the Callable is sent over the remoting channel it can do whatever it needs without ever referring to Jenkins; for example, gather any information you need on the master side before constructing the callable. If you must do a runtime check whether you are in the master or agent, use JenkinsJVM rather than this method, as merely loading the Jenkins class file into an agent JVM can cause linkage errors under some conditions.
 
 Returns:
 
 The instance. Null if the Jenkins service has not been started, or was already shut down, or we are running on an unrelated JVM, typically an agent.
 
 Since:
 
 1.653

```
@Deprecated
public List<Project> getProjects()

 Deprecated. This method will ignore Maven and matrix projects, as well as projects inside containers such as folders. You may prefer to call ItemGroup.getAllItems(Class) on AbstractProject, perhaps also using Util.createSubList(java.util.Collection<?>, java.lang.Class<T>) to consider only TopLevelItems. (That will also consider the caller's permissions.) If you really want to get just Projects at top level, ignoring permissions, you can filter the values from getItemMap() using Util.createSubList(java.util.Collection<?>, java.lang.Class<T>).

 - isUpgradedFromBefore
```
public boolean isUpgradedFromBefore(VersionNumber v)
```
 Returns true if the current running Jenkins is upgraded from a version earlier than the specified version.
 This method continues to return true until the system configuration is saved, at which point version will be overwritten and Jenkins forgets the upgrade history.
 To handle SNAPSHOTS correctly, pass in "1.N.*" to test if it's upgrading from the version equal or younger than N. So say if you implement a feature in 1.301 and you want to check if the installation upgraded from pre-1.301, pass in "1.300.*"

 Descriptor is a singleton for every concrete Describable implementation, so if a.getClass() == b.getClass() then by default a.getDescriptor() == b.getDescriptor() as well. (In rare cases a single implementation class may be used for instances with distinct descriptors.)

 getUrlChildPrefix in interface ItemGroup<TopLevelItem>
 - getRootUrl
```
@Nullable
public String getRootUrl()
 throws IllegalStateException
```
 Gets the absolute URL of Jenkins, such as http://localhost/jenkins/.
 This method first tries to use the manually configured value, then fall back to getRootUrlFromRequest(). It is done in this order so that it can work correctly even in the face of a reverse proxy.
 
 Returns:
 
 null if this parameter is not configured by the user and the calling thread is not in an HTTP request; otherwise the returned URL will always have the trailing /
 
 Throws:
 
 IllegalStateException - JenkinsLocationConfiguration cannot be retrieved. Jenkins instance may be not ready, or there is an extension loading glitch.

 - isRootUrlSecure
```
public boolean isRootUrlSecure()
```
 Is Jenkins running in HTTPS? Note that we can't really trust ServletRequest.isSecure() because HTTPS might be terminated in the reverse proxy.
 - getRootUrlFromRequest
```
@NonNull
public String getRootUrlFromRequest()
```
 Gets the absolute URL of Jenkins top page, such as http://localhost/jenkins/.
 Unlike getRootUrl(), which uses the manually configured value, this one uses the current request to reconstruct the URL. The benefit is that this is immune to the configuration mistake (users often fail to set the root URL correctly, especially when a migration is involved), but the downside is that unless you are processing a request, this method doesn't work.
 Please note that this will not work in all cases if Jenkins is running behind a reverse proxy which has not been fully configured. Specifically the Host and X-Forwarded-Proto headers must be set. Running Jenkins behind Apache shows some examples of configuration.

 Parameters:
 
 item - an item to add which is currently elsewhere
 
 name - the desired item name in this group (might simply be the original Item.getName())
 
 Returns:
 
 normally the same item, but might be a new copy if necessary
