我想從我的eclipse插件修改java源代碼。我已經提到了幾個教程，並完成了這個編碼。當我嘗試使用ASTVisitor和ASTRewrite類的代碼時。放置此代碼時代碼流將中斷。如果我刪除該塊內的代碼，該插件將運行。如何使用JDT修改源代碼？
我的意圖是從源代碼中刪除一個名爲annotaion的節點。請幫助我。我在這裏先向您的幫助表示感謝。

public boolean visit(SingleMemberAnnotation node) {
ITextFileBufferManager bufferManager = FileBuffers.getTextFileBufferManager();
IPath iPath = javaUnit.getPath();
try {
bufferManager.connect(iPath, null);

IDocument document = textFileBuffer.getDocument();
AST ast= node.getAST();
SingleMemberAnnotation singleMemberAnnotation = ast.newSingleMemberAnnotation();
singleMemberAnnotation.delete();
textFileBuffer
.commit(null , true);

finally

try {
bufferManager.disconnect(iPath, null);
