Classes compile outside vscode in CLI, but in vs-code problem section displays errors and editor highlights code lines in red

Java Code is compiling neatly, outside the Vs-Code IDE i.e., from command line and other IDE’s like IntelliJ, but when I import my project into VS-Code there are some errors displayed in problems section. Some of them are shown here with screenshots

Environment

• Operating System: Windows 10
• JDK version: 1.8 - J9 VM
• Visual Studio Code version: 1.47.2
• Java extension version: v0.64
• Build tool: Gradle, wrapper version, 4.8.1

Steps To Reproduce the

1. Create a project having src/main/resources and add your java code directly inside src\main
2. Java Model Exception: Java Model Status [Cannot nest '<project>/src/main/resources' inside '<project>/src/main'. To enable the nesting exclude 'resources/' from 'junit_tests/src/main']

Current Result

• Below is the Java language server log file excerpt

• I have tried excluding the resources folder, but no luck, problems section still has this.

• All these compile times issues or problems shown in the problems section in vsc-code are not detected in IntelliJ IDE. Not sure why the is is happening.

• The code/java intellisense cannot trace the relationship between so, red marks with lines highlighted is shown, but actually that’s not the case, as the classes are compiled perfectly from command line.

• Some of the compiler issues, shown in the problems section are -

Another oddity in this is that I can’t find sources for any of the java built-in classes, but AFAIK my settings.json is setup correctly

@dragozir Could you try replace

 "sources": "/usr/lib/jvm/openjdk-14/src.zip",

with

 "sources": "/usr/lib/jvm/openjdk-14/lib/src.zip",

or remove this line. You should install the java-14-openjdk-src package.

I have similar issue in tests as well. It shows:

The method getByIds(Collection<String>, Class<T>) in the type DataProvider
is not applicable for the arguments (Collection<String>, capture#8-of ? extends Class<? extends Identifiable>)
Java(67108979)

However, it compiles fine from command line and IntelliJ.

Here’s a piece of code:

        Stream.of(
                new Pair<>(products, Product.class),
                new Pair<>(orders, Order.class),
                new Pair<>(cars, Car.class)
        ).forEach(source -> {

            lenient().when(dataProvider.getByIds(anyCollection(), eq(source.getValue1())))
                    .thenAnswer(a -> {
                        Organization organization = (Organization) principalProvider.getPrincipal();

                        Collection<String> ids = a.getArgument(0);
                        return source.getValue0()
                                .get(organization.getCompanyId())
                                .stream()
                                .filter(p -> ids.contains(p.getId()))
                                .collect(toList());
                    });

Here’s a bit of info about my vscode
