Thanks for your assistance, but they already were. I do see the Gradle JVM is different, but I don't understand which JDK you have downloaded. Running gradlew build in console builds the mod fine, but I want to be able to debug it. The exact Run window output is: C:\Users\leon\.jdks\corretto-17.0.4\bin\java.exe -Dforge.logging.console.level=debug -Dforge.logging.markers=REGISTRIES -DlegacyClassPath.file=D:\games\minecraft_mods\forge-1.19.1_leon\build\classpath\runClient_minecraftClasspath.txt -DignoreList=bootstraplauncher,securejarhandler,asm-commons,asm-util,asm-analysis,asm-tree,asm,JarJarFileSystems,client-extra,fmlcore,javafmllanguage,lowcodelanguage,mclanguage,forge- -DmergeModules=jna-5.10.0.jar,jna-platform-5.10.0.jar -Dforge.enabledGameTestNamespaces=examplemod -Dforge.enableGameTest=true -Djava.net.preferIPv6Addresses=system -p C:\Users\leon\.gradle\caches\modules-2\files-2.1\cpw.mods\bootstraplauncher\1.1.2\c546e00443d8432cda6baa1c860346980742628\bootstraplauncher-1.1.2.jar;C:\Users\leon\.gradle\caches\modules-2\files-2.1\cpw.mods\securejarhandler\2.1.4\f47e3b9dd860a7b82154b8f90a650ffd0aaa5582\securejarhandler-2.1.4.jar;C:\Users\leon\.gradle\caches\modules-2\files-2.1\org.ow2.asm\asm-commons\9.3\1f2a432d1212f5c352ae607d7b61dcae20c20af5\asm-commons-9.3.jar;C:\Users\leon\.gradle\caches\modules-2\files-2.1\org.ow2.asm\asm-util\9.3\9595bc05510d0bd4b610188b77333fe4851a1975\asm-util-9.3.jar;C:\Users\leon\.gradle\caches\modules-2\files-2.1\org.ow2.asm\asm-analysis\9.3\4b071f211b37c38e0e9f5998550197c8593f6ad8\asm-analysis-9.3.jar;C:\Users\leon\.gradle\caches\modules-2\files-2.1\org.ow2.asm\asm-tree\9.3\78d2ecd61318b5a58cd04fb237636c0e86b77d97\asm-tree-9.3.jar;C:\Users\leon\.gradle\caches\modules-2\files-2.1\org.ow2.asm\asm\9.3\8e6300ef51c1d801a7ed62d07cd221aca3a90640\asm-9.3.jar;C:\Users\leon\.gradle\caches\modules-2\files-2.1\net.minecraftforge\JarJarFileSystems\0.3.16\e52afbb2599dc7c6f779efea0496d32fc01152e3\JarJarFileSystems-0.3.16.jar --add-modules ALL-MODULE-PATH --add-opens java.base/java.util.jar=cpw.mods.securejarhandler --add-opens java.base/java.lang.invoke=cpw.mods.securejarhandler --add-exports java.base/sun.security.util=cpw.mods.securejarhandler --add-exports jdk.naming.dns/com.sun.jndi.dns=java.naming -XX:HeapDumpPath=MojangTricksIntelDriversForPerformance_javaw.exe_minecraft.exe.heapdump "-Dos.name=Windows 10" -Dos.version=10.0 "-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2022.2\lib\idea_rt.jar=49545:C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2022.2\bin" -Dfile.encoding=UTF-8 -classpath C:\dev\minecraft_mods\forge-1.19.1_leon\build\classes\java\main;C:\dev\minecraft_mods\forge-1.19.1_leon\build\resources\main cpw.mods.bootstraplauncher.BootstrapLauncher --launchTarget forgeclientuserdev --version MOD_DEV --assetIndex 1.19 --assetsDir C:\Users\leon\.gradle\caches\forge_gradle\assets --gameDir . --fml.forgeVersion 42.0.2 --fml.mcVersion 1.19.1 --fml.forgeGroup net.minecraftforge --fml.mcpVersion 20220727.212338 Exception in thread "main" java.util.NoSuchElementException: No value present at java.base/java.util.Optional.orElseThrow(Optional.java:377) at [email protected]/cpw.mods.bootstraplauncher.BootstrapLauncher.main(BootstrapLauncher.java:141)

Using the latest version of IntelliJ IDEA Community Edition with a fresh checkout of https://docs.minecraftforge.net/en/latest/gettingstarted/ the runClient command does not work. Instead it says: Class 'cpw.mods.bootstraplauncher.BootstrapLauncher' not found in [project name]. When I try and edit the configuration and specify that class in "External Libraries", nothing happens.
