我指的是nullness-example in the docs(检查框架版本:2.1.14
)
当我按照建议运行示例来检查NullnessExampleWithWarnings.java时:
javac -processor org.checkerframework.checker.nullness.NullnessChecker docs/examples/NullnessExampleWithWarnings.java
我收到了预期的错误:
..\..\docs\examples\NullnessExampleWithWarnings.java:23: error: [assignment.type.incompatible] incompatible types in assignment.
foo = bar;
^
found : @FBCBottom @Nullable String
required: @UnknownInitialization @NonNull String
..\..\docs\examples\NullnessExampleWithWarnings.java:33: error: [argument.type.incompatible] incompatible types in argument.
foo.add(quux);
^
found : @FBCBottom @Nullable String
required: @Initialized @NonNull String
2 errors
现在我停用了Initialization checker:AsuppressWarnings=initialization
。
javac -processor org.checkerframework.checker.nullness.NullnessChecker -AsuppressWarnings=initialization docs/examples/NullnessExampleWithWarnings.java
但是这也禁用了空检查,并且构建不再报告错误。
如何禁用Initialization checker,但保留空检查?
答案 0 :(得分:1)
3.1的3.8和Checker Framework manual部分建议使用-AsuppressWarnings=uninitialized
而不是-AsuppressWarnings=initialization
。这适用于你的例子。
该建议的原因是Nullness和Initialization Checkers的实现细节:它们实际上是相同的检查器,而不是两个单独聚合在一起的检查器。
