GWT 编译器 NoSuchMethodError

Question

我的 GWT 编译器开始失败并出现 NoSuchMethodError。当我将方法参数从 Long 更新为 long 时，它开始发生。我不需要，但我尝试将其切换回来，但我仍然遇到同样的错误。我的 java eclipse 运行时编译器没有将该行视为错误，并且在开发模式下一切正常运行。

Caused by: java.lang.NoSuchMethodError: com.dscicorp.ribeye.shared.dto.Data.put(Ljava/lang/String;Ljava/lang/Long)Ljava/lang/String;

所以它似乎将 long's 和 Long's 视为不同的类型。这是实际方法的样子：

public String put(String key, long value) {
    return put(key, Long.toString(value));
}

我不确定这是否与它有关，但在错误消息中它输出的行与我的代码中的略有不同。它将长变量 "val" 替换为 "Long.valueOf(val)".

this.this.reportOptions.put("noteTypes", Long.valueOf(val))

我尝试添加长版本和长版本以查看它是否解决了这个问题，它确实解决了，但它在另一个地方出现了类似的错误。这是 GWT 错误还是我可能配置错误？

这是完整的编译器日志：

我通过创建一个新的 Eclipse 项目并导入相同的代码解决了这个问题。这可能是某种类型的缓存问题，但清除我的 gwt-unitCache 目录并没有解决它。
