Visual Studio Code not recognizing java project

VS Code is not recognizing my java project. The project is template code for a minecraft mod found here. Ive installed the plugins

• "Debugger for Java"
• "Java Extension Pack"
• "Language Support for Java by Redhat"
• "Java Test Runner"
• "Project Manager for Java"

I also get an error related to gradle.

Could not run phased build action using connection to Gradle distribution 'https://services.gradle.org/distributions/gradle-7.0.2-bin.zip'.
java.io.StreamCorruptedException: invalid type code: 00
invalid type code: 00

And here is my settings.json file

{
    "files.exclude": {
        "**/.classpath": true,
        "**/.project": true,
        "**/.settings": true,
        "**/.factorypath": true
    },
    "editor.suggestSelection": "first",
    "vsintellicode.modify.editor.suggestSelection": "automaticallyOverrodeDefaultValue",
    "java.configuration.updateBuildConfiguration": "interactive",
    "java.home": "/usr/lib/jvm/java-16-openjdk-amd64",
    "java.configuration.runtimes": [
        {
          "name": "JavaSE-1.8",
          "path": "/usr/lib/jvm/java-8-openjdk-amd64",
          "default": true
        },
    ]
}

I have no code completion for my Java files. Before it was working and in the lower right corner of visual studio it displayed the java version i was using but now it just says Java. I'm assuming its because there is a problem with gradle and thus cannot figure out my java version. Thank you for your time.

Update: This seems to work and give me auto completion but i stil get a gradle related error mention above.
