How to find ADB root path programatically?

org.jetbrains.android.sdk.AndroidSdkUtils#getAdb

It is not resolved in my project. Maybe the jar is not with me. Can you please help me to find out the jar?

It is part of Android Studio, nothing special.

I am developing in IntelliJ IDEA CE. There is no package with org.jetbrains.android.*

The external libs

Then you didn't include Android plugin as required dependency or did not choose AS as target IDE.

http://www.jetbrains.org/intellij/sdk/docs/basics/getting_started/plugin_compatibility.html

my plugin.xml looks like

<!--<depends>com.intellij.modules.lang</depends>-->

<depends>com.intellij.modules.java</depends>

<extensions defaultExtensionNs="com.intellij">
<!-- Add your extensions here -->
<toolWindow id="Json Parser" anchor="right"
factoryClass="com.jsonparse.ParserToolWindowFactory"/>
</extensions>
<actions>

<action id="ParserActionId" class="com.jsonparse.ui.action.OpenParserAction" text="Json Parser"
description="Open in Json Parser">
<add-to-group group-id="EditMenu" anchor="last"/>
<keyboard-shortcut keymap="$default" first-keystroke="ctrl shift alt J" second-keystroke="ctrl alt J"/>
</action>

</actions>
<project-components>
<component>
<implementation-class>com.jsonparse.ParserComponent</implementation-class>
</component>
</project-components>

Previously I only have

<depends>com.intellij.modules.lang</depends>. But I have added 

<depends>com.intellij.modules.java</depends>

And I rebuild my code, But there is no change

<depends>com.intellij.modules.androidstudio</depends> This one is getting error.

You must either add Android plugin to classpath of your IntelliJ Platform SDK or use Android Studio as Platform SDK instead of IntelliJ CE.

See http://www.jetbrains.org/intellij/sdk/docs/basics/plugin_structure/plugin_dependencies.

So how can I convert this existing source to Android Plugin?

Sorry, correct link is www.jetbrains.org/intellij/sdk/docs/basics/plugin_structure/plugin_dependencies.html. It has all instructions how to setup/modify setup your project.
