使用Maven生成java错误

1 年，11 月 Questions & Answers 245

在Eclipse下，我刚刚对Java代码做了一些更改，我自动创建一个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（此项目的GWT编译），最后导出包含入口点的项目的WAR（导出/WAR文件）。我必须对Jonas服务器的目录webapps/autoload发起战争。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访问应用程序服务器时，我对代码的最后更改不存在。但是，当我在localhost:8080中执行应用程序时，它们是存在的

我怀疑我的战争是由先例汇编造成的。你认为这是问题所在吗？我发现了一个问题：当我清理项目时，对于3个项目，我有一个非常普遍的错误：

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，我如何解决这个非常普遍且未解释的错误

第二，您认为这个错误是我的问题的原因吗（一个没有我上次更改的应用程序）

第三，如果没有，我可以做些什么来定位我的修改，并将其集成到应用程序中

这是Maven控制台的全部内容：

它在构建我工作区的4个项目之前停止
在这个Maven控制台（粗体）中，您可以看到，对于我工作区的至少两个项目AlizeWeb和clas2coreGwt，有一个存在构建错误
我问我上述问题是否与这些错误无关（mys last changes not put in my application server）

这是在“日志错误”视图中写入的错误：
