使用parseCpp解析C++文件时出错

Question

我试图使用Clair和Rascal来分析C++文件。

我按照Clair的Github页面上的说明将Clair添加到一个空的Rascal项目中。成功导入所需模块之后，我尝试调用parseCpp来解析C++文件，并得到以下错误：

rascal>parseCpp(|project://myproject3/myFile.cpp|);
|jar+file:///Users/rh07/.m2/repository/org/rascalmpl/clair/0.4.0/clair-0.4.0.jar!/src/lang/cpp/AST.rsc|(24317,206,<455,0>,<456,167>): Java("NoSuchMethodError","\'io.usethesource.vallang.IString org.rascalmpl.library.Prelude.readFile(io.usethesource.vallang.ISourceLocation)\'")

我怎么能让parseCpp工作呢？谢谢。

错误是由错误的版本组合造成的。请使用clair-0.5.0 (刚刚发布)，它将与Rascal VScode扩展0.5.5一起发布的rascal-0.27.2。

采用这样的pom.xml：

<dependency>
  <groupId>org.rascalmpl</groupId>
  <artifactId>clair</artifactId>
  <version>0.5.0</version>
</dependency>
