# Advanced configuration

{% hint style="info" %}
If your organization centrally manages JetBrains IDEs using JetBrains IDE Services, see the [deploy-at-scale](https://docs.sonarsource.com/sonarqube-for-intellij/getting-started/deploy-at-scale "mention") page for organization-wide deployment options, including deploying from a private plugin repository.

## HTTP configuration <a href="#http-configuration" id="http-configuration"></a>

To operate, SonarQube for IntelliJ needs to perform HTTP requests, especially in [connected-mode](https://docs.sonarsource.com/sonarqube-for-intellij/connect-your-ide/connected-mode "mention"). While SonarQube for IntelliJ will work out-of-the-box in most situations, some network infrastructure may require a custom configuration.

## Passing SonarQube for IDE properties <a href="#passing-sonarqube-for-ide-properties" id="passing-sonarqube-for-ide-properties"></a>

In SonarQube for IntelliJ, properties should be added to the IDE JVM options. Please see the [JetBrains documentation](https://www.jetbrains.com/help/idea/tuning-the-ide.html#configure-jvm-options) for more details.

## Proxy configuration

When connecting to a SonarQube instance running behind a proxy, pass your proxy settings using the [IntelliJ IDE proxy settings](https://www.jetbrains.com/help/idea/settings-http-proxy.html). In IntelliJ, go to the **Settings** > **Appearance & Behavior** > **System Settings** > **HTTP Proxy** page and select either **Auto-detect proxy settings** or **Manual proxy configuration**, and enter your details.

### HTTP Client timeouts <a href="#http-client-timeouts" id="http-client-timeouts"></a>

SonarQube for IDE supports various timeouts. Below you will find the properties added to control them:

`sonarlint.http.connectTimeout`

* Determines the timeout, in minutes, until a new connection is fully established.
* **Default**: 1 min

`sonarlint.http.socketTimeout`

* Determines the default socket timeout value, in minutes, for I/O operations.
* **Default**: infinite

`sonarlint.http.connectionRequestTimeout`

* The connection lease request timeout, in minutes, is used when requesting a connection from the connection manager.
* **Default**: 1 min

`sonarlint.http.responseTimeout`

* Determines the timeout, in minutes, until the arrival of a response from the opposite endpoint.
* **Default**: 10 min

### Server SSL certificates <a href="#server-ssl-certificates" id="server-ssl-certificates"></a>

SonarQube for IDE manages its own TrustStore in addition to the OS and Java TrustStores. When encountering an untrusted certificate, SonarQube for IDE will ask the user if the certificate should be trusted. If the answer is yes, the certificate will be added to the TrustStore.

SonarQube for IDE depends on you to provide server certificates when required by your environment. Here’s a generalization of a few basic steps you can use to help make that easier. Note that these instructions are for *server SSL certificates*. If you're dealing with a *client SSL certificate*, you'll need to create and configure a "key store" instead.

<details>

<summary>Install a server SSL certificate</summary>

**To install a server SSL certificate**

**Step 1:** Import your certificate into SonarQube for IDE. Here is a common command to import your certificate (`<Your_Certificate>.cer`) into a TrustStore (`C:/<Your_Path_To_Your_Truststore>`):

```bash
keytool -import -keystore C:/<Your_Path_To_Your_Truststore> -storepass password -noprompt -alias sonarqube-ssl -file <Your_Certificate>.cer
```

* Replace `C:/<Your_Path_To_Your_Truststore>` with your desired path and `password` with your chosen TrustStore password.

**Step 2:** Now that you’ve created the file, tell IntelliJ where to find it by adding these lines to your JVM arguments. See the [#passing-sonarqube-for-ide-properties](#passing-sonarqube-for-ide-properties "mention") instructions for more details.

```bash
-Dsonarlint.ssl.trustStorePath=C:/<Your_Path_To_Your_Truststore>

-Dsonarlint.ssl.trustStorePassword=<Your_Password>

-Dsonarlint.ssl.trustStoreType=PKCS12
```

* Check that your path and password match what you used for your TrustStore.

**Step 3:** Restart your IDE.

</details>

**TrustStore**

**sonarlint.ssl.trustStorePath**

* Path to the keystore used by SonarLint to store custom trusted server certificates
* **default**: `~/.sonarlint/ssl/truststore.p12`

**sonarlint.ssl.trustStorePassword**

* Password of the truststore.
* **default**: `sonarlint`

**sonarlint.ssl.trustStoreType**

* The format of the keystore file is found in the [Oracle documentation](https://docs.oracle.com/en/java/javase/17/docs/specs/security/standard-names.html#keystore-types).
* **default**: `PKCS12`

### Client SSL certificates <a href="#client-ssl-certificates" id="client-ssl-certificates"></a>

Some servers or proxies may also require SonarQube for IDE to authenticate using client-side SSL certificates. This is a rare use case, and at for the moment, there is no UI to configure client-side SSL certificates. To properly authenticate client-side SSL certificates, you must manually create a keystore at the default location, or use the following properties:

**KeyStore**

**sonarlint.ssl.keyStorePath**

* Path to the keystore used by SonarQube for IDE to store client certificates.
* **default**: `~/.sonarlint/ssl/keystore.p12`

**sonarlint.ssl.keyStorePassword**

* Password of the keystore.
* **default**: `sonarlint`

**sonarlint.ssl.keyStoreType**

* The format of the keystore file is found in the [Oracle documentation](https://docs.oracle.com/en/java/javase/17/docs/specs/security/standard-names.html#keystore-types).
* **default**: `PKCS12`

## Using a custom JRE <a href="#use-a-custom-jre" id="use-a-custom-jre"></a>

By default, SonarQube for IntelliJ uses the JRE provided by your IDE. It’s possible to override this and define a custom JRE as long as it meets SonarQube for IntelliJ’s [requirements](https://docs.sonarsource.com/sonarqube-for-intellij/getting-started/requirements "mention").

Please read the next section, *Passing SonarQube for IDE properties*, to add your custom `sonarlint.jre.path` system property.
