java - Proguard Maven 使用 Lambda 表达式屏蔽错误

Question

我使用 Proguard 和 Maven 来屏蔽我的 Java 代码。

我将所有函数从匿名声明更改为 Lambda 表达式0，但编译并运行后出现错误

有趣的错误日志是:

Caused by: java.lang.invoke.LambdaConversionException: Type mismatch for lambda argument 1: class com.goodsoft.stockbox.commons.model.c is not convertible to int

...所以也许 Lambda 没有问题，但是 lambda 使用的屏蔽对象没有问题？

方法之前更改为 lambda 看起来像(工作正常):

bidAskDiffChangeObserver = new BidAskDiffChangeObserver(instrument,
    new IDiffValueChangeDelegate() {
        @Override
        public void valueChanged(int newValue, ValueChangeType type) {
            mainRangeAxis.updateSpread(newValue);
        }
    });

...和 ​​AFTER 更改为 Lambda 表达式(不起作用):

bidAskDiffChangeObserver = new BidAskDiffChangeObserver(instrument,
                    (newValue, type) -> mainRangeAxis.updateSpread(newValue));

调用者:

int newValue = computeBidAskDifference();
ValueChangeType type = previousValue > newValue ? ValueChangeType.DROP :
        previousValue < newValue ? ValueChangeType.GROWTH : ValueChangeType.EQUAL;

if (delegate != null)
    delegate.valueChanged(newValue, type);

我应该使用哪个选项来添加 lambda 条件？

没有屏蔽一切工作正常(使用选项-dontoptimize)。

我在 pom.xml 中的 proguard 选项现在看起来像这样:

编辑

我尝试将 Maven 选项添加为 -optimizations !method/removal/parameter 和 -optimizations !method/marking/static 但没有帮助。

Answer 1

已解决

优化将枚举更改为整数时存在问题。

只需关闭此优化即可正常工作。

<option>-optimizations !class/unboxing/enum</option>
