Static code analysis with UTBotJava action

To analyse the Java project with UTBotJava-action you need to follow these simple steps:

1. Apply the UTBot gradle plugin to your project:

plugins {
id "org.utbot.gradle.plugin" version "1.0.0-alpha"
}

2. Create a new file <your-repository>/.github/workflows/run-utbot-java-action.yml with a workflow that can be run and configured manually:

3. On the Actions tab find the section Run UTBotJava action:

4. Click Run workflow and select the needed options:

5. After the workflow is completed, look at the Security → Code Scanning Alerts to find the detected errors (by the way, you won`t find any if your code is fine 😉):

6. Explore any alert by clicking on it:

As you see in this case above, UTBot detected an unchecked ArrayIndexOutOfBoundsException by passing the array [-192, -192] to the isSorted method.

Click Show paths button, and you see the execution trace.

📍 Note: You can find all these steps performed in our sample project: UTBotJava-action-example
