使用 maven 生成 WAR 文件时未解决的编译问题 [关闭]

Question

当我使用 mvn clean install 生成我的 WAR 文件时，一些类会抛出以下错误消息：

public Person deletePers(String paramString1, String paramString2) { throw new Error("未解决的编译问题：\n\tTransactional 无法解析为类型\n.......; }

但如果我在 Eclipse 中生成我的 WAR 文件（文件 > 导出为 War 文件），我不会收到上述错误。有谁知道如何解决这个问题？

Answer 1

问题部分：

发生这种情况是因为 Eclipse 正在使用其自己的编译器。

Eclipse 已实现其自己的编译器，称为 Eclipse Compiler for Java (ECJ)。

它不同于 javac，后者是 Sun JDK 附带的编译器。一个显着的区别是 Eclipse 编译器允许您运行代码实际上并没有正确编译。

如果出现错误的代码块从未运行过，您的程序将运行良好。否则，它将抛出一个异常，表明您尝试运行无法编译的代码。

另一个区别是 Eclipse 编译器允许在 Eclipse IDE 内进行增量构建，也就是说，所有代码在您完成输入后立即编译。

==============================

解决方案部分：

不幸的是，在 Eclipse 中没有快速的方法来切换到 Javac（来自 Sun /Oracle）。您不能简单地从 Eclipse 中的下拉菜单或类似选项中选择 javac。

仅供参考：但这是 IntelliJ IDEA 中的 very simple。

但是，您可以使用 Ant 任务或 外部工具配置 来实现。

以上两种方式都解释清楚了in this SO answers。
