The type javax.annotation.Nonnull cannot be resolved

In one of my projects, I’m getting an error after upgrading to the latest version:

The type javax.annotation.Nonnull cannot be resolved. It is indirectly referenced from required .class filesJava(16777540)
Annotation type 'javax.annotation.Nonnull' cannot be found on the build path, which is implicitly needed for null analysisJava(536871894)

I saw the changelog and found that the issue relates to enhancement - Enable annotation-based null analysis. See #1693.

Removing “javax.annotation.Nonnull” from “java.compile.nullAnalysis.nonnull” config fixes the problem for me.

Environment

• Operating System: MacOS 12.6
• JDK version: openjdk 17 2021-09-14
• Visual Studio Code version: 1.71.2
• Java extension version: 1.11.0

You should be able to disable this feature with the following settings (on the individual workspace, or globally).

.vscode/settings.json

{
    "java.compile.nullAnalysis.nonnull": [
    ],
    "java.compile.nullAnalysis.nullable": [
    ]
}

@yotov thank-you. Am able to reproduce.

Looking at the classpath of the project, I see both com.google.code.findbugs:jsr305:jar:3.0.2:runtime & org.springframework:spring-core:jar:5.3.22:compile. So basically we have 2 annotation providers on the classpath. It looks like the defaults prefer the jsr305 provides (eg. javax.annotation…) over the spring framework provider (eg. org.springframework.lang…). However clearly in this case it should be reversed.

Can you try, the following setting ? It’s basically just the default settings, but the spring framework annotations are moved to the top.

.vscode/settings.json

{
	"java.compile.nullAnalysis.nullable": [
		"org.springframework.lang.Nullable",
		"javax.annotation.Nullable",
		"org.eclipse.jdt.annotation.Nullable"
	],
	"java.compile.nullAnalysis.nonnull": [
		"org.springframework.lang.NonNull",
		"javax.annotation.Nonnull",
		"org.eclipse.jdt.annotation.NonNull"
	]
}
