Git in IntelliJ and encountering the SSL certificate issue

 

When working with Git in IntelliJ and encountering the SSL certificate issue (SSL certificate problem: self-signed certificate in certificate chain), you have several options to bypass or resolve this error:

1. Disable SSL Verification for Git in IntelliJ

This is a temporary workaround and is not recommended for secure environments.

1. Open IntelliJ and go to File > Settings (or IntelliJ IDEA > Preferences on macOS).
2. Go to Version Control > Git.
3. In the Path to Git executable field, you can temporarily bypass SSL verification by running the Git pull with an additional argument:

Ø  Change the Git command in Path to Git executable to:

bash

git -c http.sslVerify=false

 

Ø  This disables SSL verification temporarily for this session.

2. Disable SSL Verification Globally in Git (Not Recommended)

To disable SSL verification globally, you can do the following in your terminal. This affects all Git operations, including those inside IntelliJ.

bash

git config --global http.sslVerify false

 

⚠️ Warning: Disabling SSL verification globally can expose you to security risks, so this is not recommended for long-term use.

3. Add the Self-Signed Certificate to Trusted Certificates

If you have access to the self-signed certificate file, you can add it as a trusted certificate for Git.

1. Obtain the certificate file from the server or administrator.
2. In the terminal, configure Git to use this certificate:

bash

git config --global http.sslCAInfo /path/to/your-certificate.pem

 

This method lets Git validate the certificate without disabling SSL verification entirely.

4. Update Git and Git Tools

Sometimes, updating Git and its related SSL libraries can resolve certificate issues, especially if you’re using an outdated version.

Ø  Update Git using your package manager or download the latest version from Git’s official site.

 

5. Switch to SSH Instead of HTTPS in IntelliJ

Switching to SSH is a good long-term solution, as it avoids SSL issues entirely.

1. Open IntelliJ and go to File > Settings (or IntelliJ IDEA > Preferences on macOS).
2. Go to Version Control > Git and click on GitHub or your repository host.
3. Under Git Remotes, switch the remote URL from HTTPS to SSH.

bash

git@github.com:username/repository.git

 

Or

git remote set-url origin git@github.com:username/repository.git

 

4. Set up SSH keys if not already done.

6. Install the Self-Signed Certificate in Java’s TrustStore (for IntelliJ)

IntelliJ might be relying on Java’s TrustStore. You can add the certificate to Java’s TrustStore.

1. Find the location of the cacerts file for the JDK IntelliJ is using (typically in JAVA_HOME/lib/security).
2. Use the following command to import the certificate:

bash

keytool -import -alias mycert -keystore $JAVA_HOME/lib/security/cacerts -file /path/to/certificate.pem

 

3. Restart IntelliJ after adding the certificate.

7. Ensure IntelliJ Uses the Latest Git Version

Sometimes, updating Git to the latest version resolves SSL issues, as newer versions may have updated SSL libraries.

By using these solutions, you should be able to address the SSL certificate issue and resume using Git within IntelliJ effectively.

8. Trust the Certificate in Your System (for Corporate/Organization Certificates)

If you're on a corporate network, ask your IT team if they can install the organization’s root certificate into your system’s trusted certificate store. This may fix the issue across multiple applications, not just Git.

Following these steps should help resolve the SSL certificate issue with minimal security risks.
