Ошибка cannot access java lang string

I was setting up a java/kotlin library for my android project in which i was creating a data class (model) with moshi converter. But the issue is the annotation @JsonClass and at other places i am getting this error

Cannot access class ‘java.lang.String’. Check your module classpath for missing or conflicting dependencies

**EDIT: solved.**

Apprently my project structure -> platform settings -> sdk -> 11 was pointing to some non-existent jdk 11 in the intellij install directory. Not sure why that wasn’t showing an error. The fix was I edited that setting to point to my local install jdk 11.

So I’m having a strange issue I can’t seem to find a solution for. I have created a small spring boot project using the built in spring initializer in intellij, i chose kotlin and java 11. My build.gradle.kts is setup for java 11 as well.

I can build and run my project just fine. But intellij is showing errors all over my source files. It seems as though intellij itself is confused. It is saying things like: «Cannot access java.lang.String. Check your module classpath for missing of conflicting dependencies»

In file -> project structure -> project -> project sdk: i have java 11 selected (my installed version)

And here is my build.gradle.kts:

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

    id("org.springframework.boot") version "2.2.0.RELEASE"
    id("io.spring.dependency-management") version "1.0.8.RELEASE"

cannot resolve method ‘getParameter(java.lang.String)’

Вы столкнулись с этой проблемой?

Изначально использовал Myeclipse, позже перешел на IDEA, различные проблемы не решаются, эта проблема одна из них.

У него также есть проблема с братом:

cannot resolve method ‘println(java.lang.String)’

Рисунок выше — это скриншот кода после решения.

Решение:

1. Очистите кеш

Нажмите «Файл» в верхнем левом углу —-> «Недействительные кеши / перезагрузка».

В появившемся диалоговом окне нажмите «Invalidate».

Если этот метод не работает, обратитесь ко второму способу.

2. Добавьте кота

Нажмите «Файл» в верхнем левом углу ——> Структура проекта

В новом диалоговом окне нажмите «Модули» —-> «+» —-> «Библиотека или зависимость модуля ..»

Появится диалоговое окно, выберите кот ——> нажмите «Добавить выбранное».

Нажмите «Применить» —-> «ОК»

3. Альтернативный метод

Если вы не можете решить эту проблему, попробуйте вернуться к методу 1: «Файл» —-> «Недействительный кеш / перезапуск» —-> во всплывающем диалоговом окне нажмите «Недействительность и перезапуск».

Хорошо, на данный момент моя проблема решена.

заметка:

Операционная система: win7

JDK：1.6

Решение: сначала устраните проблему, чтобы найти причину, а затем слепо измените ее и продолжайте попытки и ошибки. В то же время браузер ищет похожие проблемы и, наконец, решает их.

Hmm.. I have some problems with this new quest system I coded for my RuneScape private server…
My compiler says this:

.palidino76rs2QuestsAfriendoftheKingdom.java:14: cannot find symbol

ino76.rs2.Quests.Quests cannot be applied to (java.lang.String)

setFinalStage("7");//Final stage. "setFinalStage" is a string/void I created to

decide in which stage the quest ends.

Note: .palidino76rs2QuestsQuestloader.java uses unchecked or unsafe operatio

ns.

Note: Recompile with -Xlint:unchecked for details.

2 errors

Tryk på en vilkårlig tast for at fortsætte . . .

So as you see my errors is in my AfriendoftheKingdom file. (The name of the quest I want to create.)
And my Quest file..
So here is my AfriendoftheKingdom program.

package palidino76.rs2.Quests;

import palidino76.rs2.players.*;

import java.io.*;

import palidino76.rs2.net.SocketListener;

import palidino76.rs2.util.*;

import palidino76.rs2.Engine;

import palidino76.rs2.io.*;

public abstract class AfriendoftheKingdom extends Quests {

public AfriendoftheKingdom(Player owner, Integer uid) {

super(owner, uid);

}

protected String name = "A friend of the Kingdom.";

protected int uid = 10;

protected int stage = -1;

protected int finalStage = 7;

/**

*A public void made to define the quest name, and in which stage it ends.

*/

public void define()

{

setName("A knight of Vimsie");//Quest name. "setName" is a string I created to set the name of the quest.

setFinalStage("7");//Final stage. "setFinalStage" is a string/void I created to decide in which stage the quest ends.

}

/**

*This method will be used when the public final int getFinalStage is met.

*Which in this case is 7.

*/

public void completeQuest(Player p)

{

/**

*The Engine shortcut that will be called below here, will be the reward when the quest is completed.

*/

Engine.playerItems.addItem(p, 995, 1000);

sleep(2500);//Like the public void process delays something with 600 milliseconds, this statement (sleep) will delay something with the milliseconds entered in the ().

p.frames.sendMessage(p, "You have completed " + getName() + "and are now a friend of the Kingdom!");

p.frames.sendMessage(p, "@[email protected] You just gained 1 quest point.");

}

}

My compiler says the error is in this line.

super(owner, uid);

and heres the public the super(owner, uid); thing belongs to.

public AfriendoftheKingdom(Player owner, Integer uid) {
  super(owner, uid);
}

So that is the cannot find symbol error..
And here is my Quest file where the cannot find symbol (java.lang.String) error is located…

package palidino76.rs2.Quests;

     }

}

That’s the Quest program, I do know what creates this cannot be applied to (java.lang.String) error..
The problem is this line

setFinalStage("7");//Final stage. "setFinalStage" is a void I created to decide in which stage the quest ends.

in my AfriendoftheKingdom program..
But I know what the deal is..
It is the public void setFinalStage(int stage)
{
in my Quest program.. My compiler says that

setFinalStage("7");

cannot be called by a public void, but it needs to be called by a String and not a void..
But that’s where my question comes..
How can it be that this line

setName("A knight of Vimsie");

in AfriendoftheKingdom, can be called by a public void then setFinalStage(«7»); can’t when the public voids in the Quest program is almost the same?????
Here’s the setFinalStage void from the Quest program..

     /**
      * Sets the final stage of this quest.
      */
     public final void setFinalStage(int stage)
     {
      this.finalStage = stage;
     }

And here’s the setName void from the Quest program…

     /**
      * Changes the name of this quest.
      */
     public final void setName(String name)
     {
      this.name = name;
     }
