reverse the arguments here. It's expected, actual.

The changes LGTM, as for the test part, I suggest to add a test case not including jsr 305 in the pom (in any scope), and test this project would be imported successfully. e.g., sample project in redhat-developer/vscode-java#2712 (comment)

how about directly use ClasspathOptions.scope = "runtime" in https:/eclipse/eclipse.jdt.ls/blob/f8452b422add64f9bbc80d0e22b48ed71797e563/org.eclipse.jdt.ls.core/src/org/eclipse/jdt/ls/core/internal/preferences/Preferences.java#L2055

in this way, we can avoid checking classpath entry attribute here.

Agree. We could exclude test scope directly when getting the project classpaths.

it seems that using ClasspathOptions.scope = "runtime" doesn't work in this case. I just tested sample project in redhat-developer/vscode-java#2712 (comment) and see the introduced artifact jsr 305 is in runtime scope:

So the scope filter won't filter this dependency. However, in the classpath entry, it has test attribute:

So the new introduced method isTest() works. it will check the attributes of the classpath entry.

and I also tried ProjectCommand.isTestClasspathEntry() mentioned by @jdneo , it also checks the attribute and it works well. So it seems that we don't need to add a new method.

~~This is a bug on the utility method ProjectCommand.getClasspathsFromJavaProject, which never uses the passed scope parameter.~~

In the launch configuration template JAVA_APPLICATION_LAUNCH, we could use the following attribute to exclude test code.
<booleanAttribute key="org.eclipse.jdt.launching.ATTR_EXCLUDE_TEST_CODE" value="true"/>

The launch configuration dynamically returns the scope value.

If the resolve logic doesn't filter the test scope directly, then it's a bug of JavaLaunchDelegate.getClasspathAndModulepath that doesn't handle the test scope well.

I'm OK to filter it on jdt.ls side.

It's interesting that the test attribute is set to true but the maven.scope is runtime.

Is that a bug of m2e?

which never uses the passed scope parameter.

It will,

FYI the jsr305 dependency is declared as implementation scope, not test in spring-kafka: https:/spring-projects/spring-kafka/blob/4bcb503a2fb33d20b45f4cc241c769c397bf0a7d/build.gradle#L173

CsCherrYY · 2022-10-08T09:10:42Z

it seems that jsr305 introduced by spring-kafka is in runtime scope, which make the null annotation types are not avaiable in project, but the jsr305 jar still appears in default classpath we get from getClasspathsFromJavaProject():

maybe we can check the classpath attribute maven.scope=runtime. Besides, I'm not so sure why test tag is introduced by m2e, maybe related to eclipse-m2e/m2e-core#543, but besides checking test tag, checking maven.scope is good IMO. (Do all the runtime classpath entries are tagged by test? maybe @fbricon and @rgrunber can provide some thoughts here)

As for Gradle projects, directly use implementation 'org.springframework.kafka:spring-kafka:2.9.1' will add the dependency in both compileClasspath and runtimeClasspath (which means the null annotation types are available in the project), there will be no such error.

It is intentional. See https:/eclipse-m2e/m2e-core/blob/master/org.eclipse.m2e.jdt/src/org/eclipse/m2e/jdt/internal/DefaultClasspathManagerDelegate.java#L164

The https:/yotov/vscode-nullable project includes jsr 305 indirectly. It is the same as the maven/null-analysis.

maven recognizes it as runtime

that's what I found and suggested in #2264 (comment), if all the runtime classpath entries have test attribute, then I'm OK with this change. It seems that they are related: https:/eclipse-m2e/m2e-core/blob/0223a44258a6c92ac4a1943721a983743809ac37/org.eclipse.m2e.jdt/src/org/eclipse/m2e/jdt/internal/DefaultClasspathManagerDelegate.java#L125

The https:/yotov/vscode-nullable project includes jsr 305 indirectly.

You're right. I just misunderstood that the project doesn't have jsr 305 dependency.

rgrunber · 2022-10-11T17:08:49Z

Yeah intuitively it made sense to me. runtime is basically saying "you don't need this dependency to compile, but it should be present when running the application". But running the tests also involves running the application, so the behaviour makes sense.

I think this is ready to be merged.
