🚀 Solving the Bytecode Inlining Error in IntelliJ

So you're trying to run the Example CorDapp from the GitHub CorDapp repository using IntelliJ, but you're encountering a frustrating error message:

Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6

Don't worry, we've got you covered! In this guide, we'll address this common issue and provide you with easy solutions to fix it. Let's get started!

📝 Understanding the Problem

The error message is informing you that you're trying to inline bytecode that was built with Java Virtual Machine (JVM) target version 1.8 into bytecode that is being built with JVM target version 1.6. This is not allowed because later versions of Java may contain features or optimizations that are not available in earlier versions.

💡 Solution 1: Updating JVM Target

The most straightforward solution is to update the JVM target in IntelliJ to match the bytecode version you're trying to inline.

  1. Open your project in IntelliJ.

  2. Go to File > Project Structure.

  3. In the Project Structure dialog, navigate to Project Settings > Modules.

  4. Select your module and click on the Dependencies tab.

  5. Locate the dependency that is causing the error.

  6. In the Bytecode Version column, click on the dropdown menu and select the appropriate JVM target version (in this case, version 1.8).

  7. Click OK to save the changes.

By updating the JVM target, you ensure that all the bytecode in your project is built with the same version, resolving the error.

💡 Solution 2: Checking the Java Compiler Settings

If Solution 1 does not resolve the issue, it's possible that the Java Compiler settings in IntelliJ are misconfigured. Let's check and make sure everything is set correctly.

  1. Open your project in IntelliJ.

  2. Go to File > Settings.

  3. In the Settings dialog, navigate to Build, Execution, Deployment > Compiler > Java Compiler.

  4. Check the Target bytecode version. Ensure it is set to the correct version (in this case, 1.8).

  5. Click OK to save the changes.
