Cannot create abstract class in codemodel?

My code:

JCodeModel cm = new JCodeModel();
cm._class(JMod.ABSTRACT, "TestClass", ClassType.CLASS);
cm.build(new File("."));

no matter what I write to mods or ClassType parameter, the outcome is always a public class.

How can I create an abstract class?

Solution

  • Strange. It seems JCodeModel doesn't create abstract classes without a package. The following cases have a package declaration:

    JCodeModel cm = new JCodeModel();
cm._class(JMod.PUBLIC | JMod.ABSTRACT, "test.TestClass", ClassType.CLASS);
cm.build(new File("."));

    Generates:

    package test;

public abstract class TestClass {

}

    or

    JCodeModel cm = new JCodeModel();
JPackage pkg = cm._package("");
pkg._class(JMod.ABSTRACT, "TestClass2", ClassType.CLASS);
cm.build(new File("."));

    Generates:

    public abstract class TestClass2 {

}
