【问题】

在折腾:

【记录】尝试使用ANTLRWorks 2.0去进行ANTLR开发

的过程中,用ANTLRWorks 2.0编译运行Hello.g4,结果出现警告和错误:

warning Supported source version RELEASE_6 from annotation processor

全部log为:

【解决过程】

1.很明显,看起来像是,不支持JAVA7,希望的版本是JAVA6。

2.所以去:

卸载当前的JDK7

3.去

http://www.oracle.com/technetwork/java/javase/archive-139210.html

Java SE 6

下载到:

jdk-6-windows-amd64.exe

重新安装JDK 6。

4.然后再次运行,此警告就消失了。

 

【总结】

貌似ANTLRWorks 2.0,不支持JDK 7?

不过后来的结果证实,貌似JDK 7,好像没有对antlrworks产生本质的影响,即

不论是jdk6还是jdk7,其实都不影响antlrworks的使用的。


接下来,就是去解决对应的error了:

【未解决】ANTLRWorks 2.0编译Hello.g4文件结果出错:line 1:0 token recognition error at: ‘W’
