Answer 1

打开项目文件夹打开Package.json并添加＆＃34; reflect-metadata＆＃34;：＆＃34; ^ 0.1.3＆＃34;，

在文件夹上运行npm install - ＆GT; ionic不再将反射元数据添加到package.json

Answer 2

@Kishore Kumar的答案是正确的但你需要在那之后进行npm重建..所以

在Ionic项目中，打开：

的package.json

在其中添加：

package org.sonar.template.java.checks;

import com.google.common.collect.ImmutableList;

import org.sonar.check.Priority;
import org.sonar.check.Rule;
import org.sonar.plugins.java.api.semantic.Symbol;
import org.sonar.plugins.java.api.semantic.Symbol.TypeSymbol;
import org.sonar.plugins.java.api.IssuableSubscriptionVisitor;
import org.sonar.plugins.java.api.tree.*;
import org.sonar.plugins.java.api.tree.Tree.Kind;

import java.util.List;

@Rule(
    key = "SharedPreferencesRule",
    name = "Utilização de SharedPreferences no código",
    description = "Para cada utilização de SharedPreferences, é feito um alerta para revisar o que está sendo armazenado.",
    priority = Priority.CRITICAL,
    tags = {"attention point", "security"})
public class SharedPreferencesCheck extends IssuableSubscriptionVisitor {

    @Override
  public List<Kind> nodesToVisit() {
    return ImmutableList.of(Kind.METHOD_INVOCATION);
  }

  @Override
  public void visitNode(Tree tree){
      System.out.println("====================== Kind Finded ======================");

      MethodInvocationTree kindTree = (MethodInvocationTree) tree;

      Symbol symbol = (Symbol) kindTree.symbol();

      TypeSymbol classe = symbol.owner().enclosingClass();

      System.out.println("Name >>>>>>>>>>>>> " + symbol.name());
      System.out.println("Enclosing >>>>>>>>>>>>> " + classe);

      if (classe != null && classe.equals("SharedPreferences")){
          reportIssue(kindTree.firstToken(), "SharedPreferences sendo utilizado no código. Analisar!!");
      }

  }
}

然后在控制台上运行： "reflect-metadata": "^0.1.3",

然后运行：npm install

准备好运行npm rebuild以查看您的应用;）
