我使用custom rule代码段创建了一个自定义规则插件。现在我添加了另一个规则，当匿名类有超过30行时会显示错误。
我使用mvn package命令构建自定义规则插件jar并放入声纳服务器扩展/插件并重新启动服务器。
我的相应规则可以从声纳服务器查看，但规则不能分析代码，尽管有一个类具有loc> 30行的匿名类。我的自定义规则如下。
@Rule(
key = AnonymousClassesTooBigCheck.KEY,
name = "Avoid too big classes",
description = "avoid too bid classes",
tags = {"brain-overload"},
priority = Priority.MAJOR)
@BelongsToProfile(title = "Sonar way", priority = Priority.MAJOR)
public class AnonymousClassesTooBigCheck extends BaseTreeVisitor implements JavaFileScanner {
public static final String KEY = "AD0001";
private static final RuleKey RULE_KEY = RuleKey.of(MyJavaRulesDefinition.REPOSITORY_KEY, KEY);
private static final int DEFAULT_MAX = 30;
@RuleProperty(defaultValue = "" + DEFAULT_MAX)
public int max = DEFAULT_MAX;
private JavaFileScannerContext context;
/**
* Flag to skip check for class bodies of EnumConstants.
*/
private boolean isEnumConstantBody;
@Override
public void scanFile(JavaFileScannerContext context) {
this.context = context;
isEnumConstantBody = false;
scan(context.getTree());
}
@Override
public void visitNewClass(NewClassTree tree) {
if (tree.classBody() != null && !isEnumConstantBody) {
int lines = getNumberOfLines(tree.classBody());
if (lines > max) {
context.addIssue(tree, RULE_KEY, "Reduce this anonymous class number of lines from " + lines + " to at most " + max + ", or make it a named class.");
}
}
isEnumConstantBody = false;
super.visitNewClass(tree);
}
@Override
public void visitEnumConstant(EnumConstantTree tree) {
isEnumConstantBody = true;
super.visitEnumConstant(tree);
}
@Override
public void visitLambdaExpression(LambdaExpressionTree lambdaExpressionTree) {
int lines = getNumberOfLines(((JavaTree) lambdaExpressionTree.body()).getAstNode());
if (lines > max) {
context.addIssue(lambdaExpressionTree, RULE_KEY, "Reduce this lambda expression number of lines from " + lines + " to at most " + max + ".");
}
super.visitLambdaExpression(lambdaExpressionTree);
}
private int getNumberOfLines(ClassTree classTree) {
int startLine = ((InternalSyntaxToken) classTree.openBraceToken()).getLine();
int endline = ((InternalSyntaxToken) classTree.closeBraceToken()).getLine();
return endline - startLine + 1;
}
private int getNumberOfLines(AstNode node) {
return node.getLastToken().getLine() - node.getTokenLine() + 1;
}
}
现在我需要做更多的事情才能获得规则吗？
还有一件事
将插件jar放入插件文件夹后，如果我使用mvn sonar:sonar运行分析器，则会出现错误

答案 0 :(得分：0)
您遇到此错误的原因是AnonymousClassesTooBigCheck的代码正在使用内部API，此处InternalSyntaxToken不应该直接使用，因此在运行时失败（您可能会注意到custom rule代码段中的示例正在使用此类）。
