JDT - 如何從 CompilationUnit 獲取 ICompilationUnit

Question

這是我的代碼。 我正在那里制作一個 CompilationUnit

ASTParser parser = ASTParser.newParser(AST.JLS8);
parser.setResolveBindings(true);
parser.setStatementsRecovery(true);
parser.setBindingsRecovery(true);
parser.setKind(ASTParser.K_COMPILATION_UNIT);
parser.setEnvironment(getProjectJars(), getSrcPaths(), null, true);

parser.setSource(IOUtils.toCharArray(new FileInputStream(MY_SRC_FILE)));
parser.setUnitName(MY_SRC_FILE.getAbsolutePath());

CompilationUnit cu = (CompilationUnit) parser.createAST(null);

如何從源代碼制作的 CompilationUnit 中獲取 ICompilationUnit？ 謝謝

Answer 1

我找到了解決方案：

IWorkspace workspace = ResourcesPlugin.getWorkspace();
IPath path = Path.fromOSString(source.getAbsolutePath());
IFile file = workspace.getRoot().getFileForLocation(path);
ICompilationUnit compilationUnit = (ICompilationUnit) JavaCore.create(file);

Answer 2

我試過了，它奏效了：

ICompilationUnit cu= (ICompilationUnit)compilationUnit.getJavaElement();

Answer 3

第一個選項如下：

ICompilationUnit compilationUnit = JavaCore.createCompilationUnitFrom(javaFile);  
types = compilationUnit.getAllTypes();

第二個選項如下：

IProject project = javaFile.getProject(); 
IJavaProject jProject = JavaCore.create(project); 
if (jProject == null || !jProject.exists()) 
{   
   return null; 
} 
IPackageFragment packageFragment = null; 
try {   
   packageFragment = jProject.findPackageFragment(
                         javaFile.getFullPath().removeLastSegments(1));     
   String unitName = javaFile.getName();    
   ICompilationUnit cu = packageFragment.getCompilationUnit(unitName);  
   return cu; 
} catch (JavaModelException e) {    
return null; 
}
