我需要使用getAST()方法从源文件中获取AST。我创建了一个.cproject,因为我认为它是一个缺失的,但它仍然犯了同样的错误。在这部分代码:我无法从c源代码使用cdt plugin eclipse获取AST
ITranslationUnit tu = (ITranslationUnit) CoreModel.getDefault(). Create (iFile);
是返回null的恩,我认为错误是因为这一点,但我不明白为什么它返回NULL,如果我用一个.cproject CDT项目测试。我也不明白IFile,因为它返回了我不知道的路径,如下所示:“L/Users/raiza arteman/runtime -EclipseApplication/testeAST/src/code.c”。下面是类:
public void analyzeFilesInSrc() throws Exception{
ICProject project = CoreModel.getDefault().getCModel().getCProject(SampleHandler.PROJECT);//project to analyse
IIndex index = CCorePlugin.getIndexManager().getIndex(project);
System.out.println("iindex "+index);
// It gets all C files from the SRC path to analyze.
this.filesInSrc = new ArrayList<String>();
this.setSrcFiles(SampleHandler.RUNTIME_WORKSPACE_PATH + SampleHandler.PROJECT + File.separator + "src");
// For each C file in the SRC folder..
for (String file : this.filesInSrc){
String completeFilePath = file.replace(SampleHandler.RUNTIME_WORKSPACE_PATH, "");
System.out.println(completeFilePath.replace(PROJECT + File.separator + "src" + File.separator, ""));
this.editDirectives(file);
IPath iFilePath = new Path(completeFilePath);
IFile iFile = ResourcesPlugin.getWorkspace().getRoot().getFile(iFilePath);
System.out.println("ifile "+iFile);
System.out.println("Itranslatiotounit "+(ITranslationUnit) CoreModel.getDefault().create(iFile));
ITranslationUnit tu = (ITranslationUnit) CoreModel.getDefault().create(iFile);
System.out.println("tu "+tu);
try {
// We need a read-lock on the index.
index.acquireReadLock();
IASTTranslationUnit ast= tu.getAST(index, ITranslationUnit.AST_PARSE_INACTIVE_CODE);
this.setTypes(ast);
this.setMacros(ast);
}
正在发生的事情是:
java.lang.NullPointerException

我可以在CDT项目中使用此之后,我需要解析的任何C代码,即使它是不是从CDT ,为此,我在这里看到了一个将.cproject文件放入项目根目录的建议。
