我正在使用IntelliJ IDEA 15.0.4开发一个GWT项目.该项目编译并运行.但是IntelliJ一直告诉我JRE Emulation Library中没有java类文件.
请帮我!我的maven pom.xml中缺少什么东西吗?
我的pom.xml:
<properties>
   <maven.compiler.target>1.8</maven.compiler.target>
   <maven.compiler.source>1.8</maven.compiler.source>
</properties>

    除非您有完整版本的 IntelliJ,否则我强烈建议您使用 Eclipse + GWT 插件进行 GWT 开发。
这是 GWT Jre 模拟类的参考,这里的所有内容都将在客户端工作: http ://www.gwtproject.org/doc/latest/RefJreEmulation.html#Package_java_io
在您的特定情况下,IntelliJ 似乎也找不到 String 类,这表明比 GWT 相关的配置问题更深层次。
