Unknown variable type java.util.Map<java.lang.String,java.lang.Integer> for declared

[vanniktech]

I don't know if I am doing something wrong but this seems odd to me.

To reproduce this:

@Test
public void testMap() {
    final JavaFileObject actualSource = JavaFileObjects.forSourceString("test/MapTest", Joiner.on('\n').join(
        "package test;",

        "import nsmodelextractor.Extract;",

        "import java.util.Map;",
        "import java.lang.String;",
        "import java.lang.Integer;",

        "public class MapTest {",
            "@Extract Map<String, Integer> map = null;",
        "}")
    );

    assertAbout(javaSource()).that(actualSource).compilesWithoutError();
}

The extract annotations looks like this

@Retention(CLASS)
@Target(FIELD)
public @interface Extract {
    String name() default "";
}

I also tried it without any imports. However I keep on getting

Unknown variable type java.util.Map<java.lang.String,java.lang.Integer> for declared

I'm using com.google.testing.compile:compile-testing:0.7

That errors also exists in com.google.testing.compile:compile-testing:0.8

I haven't tried this, but could the problem be that you need to make nsmodelextractor.Extract available to the compiler, either by including its source or by supplying a -classpath?

[vanniktech]

No. Since everything works fine when I use primitive types or types like String, Integer, Float etc. As an example, the Java File class below works perfectly fine.

final JavaFileObject actualSource = JavaFileObjects.forSourceString("test/MapTest", Joiner.on('\n').join(
    "package test;",

    "import nsmodelextractor.Extract;",

    "public class MapTest {",
        "@Extract int myInt",
        "@Extract float myFloat",
        "@Extract double myDouble",
        "@Extract Integer myInteger",
        "@Extract Float myFloat",
        "@Extract String myString",
    "}")
);

I'm not able to reproduce the problem. Can you paste the complete failure output?

[eamonnmcmanus]

Also, is this a failure when you are running from within Eclipse, by any chance?

[vanniktech]

I'm running Android Studio 1.5 Preview.

Failure output:

java.lang.AssertionError: Compilation produced the following errors:

This error happens in Android Studio when I run the tests, as well as in the Terminal when I run ./gradlew clean test

[eamonnmcmanus]

That's a different failure from what you said initially, due to using java.lang.Map instead of java.util.Map.

[vanniktech]

That's right. Seems like I mixed it up. Sorry for the confusion.
