使用Maven进行错误构建

Question

在Eclipse下，我刚刚对Java代码进行了一些更改，然后，我自动进行了Clean / Build（清理我的4个项目），然后对包含入口点的项目进行GWT编译（该项目的GWT编译） ，最后导出包含入口点（导出/战争文件）的项目的WAR。 我必须将WAR放在Jonas服务器的目录webapps / autoload中。 我停止Jonas服务器，然后重新启动Jonas服务器。

问题是：当我通过Internet Explorer到达应用程序服务器时，我的代码的最新更改不存在。 但是，当我在localhost：8080中执行应用程序时，它们存在。

我怀疑我的WAR是根据先例编译创建的。 您是否认为这是问题所在？ 而且我看到一个问题：当我清理项目时，对于3个项目，我有这个非常普遍的错误：

27/09/12 20:16:36 CEST: Build errors for my_project;
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal
org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project alizesWeb: Compilation failure

首先，我该如何解决这个非常笼统且无法解释的错误？

其次，您是否认为此错误是我的问题的原因（没有我的最后更改的应用程序）。

第三，如果没有，我该怎么做才能将修改后的内容集成到应用程序中？

这是Maven控制台的全部内容：

在构建我的工作区的4个项目之前，它会停止。
在此Maven控制台中，以粗体显示的是，我的工作区中至少有两个项目alizesWeb和clas2coreGwt，其中一个存在构建错误。
我问我这些错误是否与上述问题无关（我的最新更改未放在我的应用程序服务器中）

这是写在“日志错误”视图中的错误：

Answer 1

编译失败意味着您的代码无法编译，因此这是没有可行的jar / war的原因，是的。

Eclipse应该在问题所在的“问题”视图（窗口->打开视图）中告诉您。 该消息很笼统，就像您说的那样，因此您需要找出详细信息才能进行修复。
