Similarly 58.65535 stands for Java 14 preview. The class file version 57.65535 stands for Java 13 preview, where the major version 57 stands for Java 13, the minor version 65535 stands for preview feature. The compiled classes are not compatible with the runtime JDK. Program throws UnsupportedClassVersionError

If you have recently modified the pom.xml or adle config file, you need right click on pom.xml or adle file and then run the menu "Update project configuration" to force the language server to update the project configuration/classpath. Check whether you configure the required libraries in the dependency settings file (e.g. This error indicates your application attempts to reference some classes which are not found in the entire classpaths. Program throws ClassNotFoundException Reason: Please reference the language server troubleshooting paragraph for more troubleshooting info. If the problem persists, it's probably because the language server doesn't load your project correctly. Run VS Code command "Java: Force Java compilation" to rebuild your workspace. Check the Java file you are running is under any source path? If not, go to File Explorer, right click the folder containing your Java file, and run the menu "Add Folder to Java Source Path" to mark the containing folder as a Java source root. Run VS Code command "Java: List all Java source paths" to show all source paths recognized by the workspace. 
Check whether the class name specified in mainClass exists and is in the right form. You configure the incorrect main class name in mainClass of launch.json, or your Java file is not on the classpath. Program Error: Could not find or load main class x Reason: Run VS Code command "Java: List all Java source paths" to check whether the containing folder is added as a Java source root. Go to File Explorer, right click the folder containing your Java file, and run the menu "Add Folder to Java Source Path" to mark the containing folder as a Java source root. If you try to run or debug this Java file, you may get the error "Could not find or load main class". class file will be generated because Java language server only auto builds Java source files on the project classpath. 
This error indicates the Java file you opened isn't on the classpath of any project, and no. Only syntax errors will be reported Reason:
If still cannot find out what errors, then reference the language server troubleshooting paragraph to update project configuration, and clean workspace cache. Run VS Code command "Java: Open Java language server log file", search keyword build/building workspace to find more details for the build errors. Open VS Code PROBLEMS View, and fix the errors there. One is compilation error for source code, the other is project error. The error indicates your workspace has build errors. Try more troubleshooting guide from the language server product site.īuild failed, do you want to continue? Reason:. Run VS Code command "Java: Clean the Java language server workspace" to clean the stale workspace cache. Open your Maven pom.xml file or Gradle adle file, then run VS Code command "Java: Update project configuration" to force the language server to update the project configuration/classpath. If you get the error "The JAVA_HOME environment variable points to a missing folder" or "Java runtime could not be located", please make sure that the environment variable JAVA_HOME points to a valid JDK. You should see the 👍 icon if the language server is loaded correctly. java or a Java project folder in VS Code, and then check the icon at the right side of the status bar. 
Here is a simple way to check whether the language server is started. If the language server fails to start, the debugger will not work as expected. The debugger works with Language Support for Java(TM) by Red Hat (the language server) for source mapping and project support. Java Language Support extension fails to start. If it does not cover the problem you are seeing, please log an issue instead. This document provides the information needed to troubleshoot common errors of Debugger for Java (the debugger).
