I have a code like this:
protected <T> T doSomething(String someParam, Class<T> clazz) {
...
}
which I use in a TestCase class:
Class clazz = MyClass.class;
MyClass MyClass = someObject.doSomething(someString, clazz);
This code gives a warning in eclipse:
Class is a raw type. References to generic type Class should be parameterized
and
Multiple markers at this line
- Type safety: Unchecked invocation doSomething(String, Class) of the generic method doSomething(String, Class) of type MyClass
- Type safety: The expression of type Class needs unchecked conversion to conform to Class
When I run this code (test) in eclipse - everything works perfectly. When I do it through "mvn clean install" through command prompt, I get:
C:\pathToProject\src\test\java\packagesPath\MyTestCase.java:[xx,xxx] incompatible types found :
java.lang.Object
required: com.somePackagePath.MyClass
But when providing:
Class<MyClass> clazz = MyClass.class;
MyClass MyClass = someObject.doSomething(someString, clazz);
I don't get any errors nor warnings. .
I understand that java compiler erases type info, so:
Shouldn't eclipse provide a compiler error instead of warning, or is it the maven-plugin-compiler that creates the problem?
The maven plugin is:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
<showDeprecation>false</showDeprecation>
<debug>true</debug>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
Kind Regards,
