项目的输出目录应设置为/ gwtproject/src/main/webapp/WEB-INF/classes

Question

我使用New-> Project-> Maven project-> GWT Eclipse插件在Eclipse中创建了一个GWT Maven项目.它被创建了,但它给出了一些错误

The output directory for the project should be set to /gwtproject/src/main/webapp/WEB-INF/classes

配置项目时是否有任何遗漏？

我的pom.xml包括:

<build>
        <!-- Generate compiled stuff in the folder used for developing mode -->
        <outputDirectory>${webappDirectory}/WEB-INF/classes</outputDirectory>
        <plugins>

Answer 1

这个问题的一个超常解决方案是:

1. 在Package Explorer中选择项目.
2. 打开项目的属性.
3. 选择Java Build Path

4. 更改默认输出文件夹

5. 质疑你在Eclipse中做出的生活决定.
