我有以下Java类的小部分：
public class GBitMaskTest {
@Test
public void checkFirstBitTest() {
BitMask bm = new BitMask(0x8000000000000000L);
assertEquals(true, bm.isBitSet(63));
}
...
}
这段代码应该可以在Groovy中被编译，因为它是有效的Java代码。但是我却得到了以下错误：
Groovy Bug --- exception in phase 'conversion' in source unit '/home/g-ut-example/src/test/groovy/com/soebes/training/maven/simple/GBitMaskTest.groovy' For input string: "8000000000000000"
BUG! exception in phase 'conversion' in source unit '/home/g-ut-example/src/test/groovy/com/soebes/training/maven/simple/GBitMaskTest.groovy' For input string: "8000000000000000"
也许我对某个事情有误解。有人有想法吗？
这种情况发生在Groovy 2.0与Maven的关系中。它是在这个例子中出现的：https://github.com/khmarbaise/maui/tree/master/src/main/resources/g-ut-example，它产生了这个问题。我正在使用以下部分进行编译：
