I was also running into the same issue from the command line on my Mac, but the answer was that <code>JAVA_HOME</code> was getting overridden. To track down where it is getting overridden first check java from the command line:

<pre><code>$ java -version
java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)
</code></pre>

Then check which version of Java that Gradle is using:

<pre><code>$ gradle -version

Groovy: 2.4.4
Ant: Apache Ant(TM) version 1.9.6 compiled on June 29 2015
JVM: 1.8.0_92 (Oracle Corporation 25.92-b14)
OS: Mac OS X 10.11.5 x86_64
</code></pre>

At this point, I still hadn't found the source of the problem. Did a little digging, and found that it was indeed overridden in my <code>gradle.properties</code> file even though it was showing Java 8 when I executed <code>gradle -version</code>:

<pre><code>org.gradle.daemon=true
org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home
org.gradle.jvmargs=-XX:MaxPermSize=512m -XX:-UseSplitVerifier -Xms512m -Xmx6144m
</code></pre>

To fix, I just deleted the <code>java.home</code> line from <code>gradle.properties</code>. Hopefully this helps if anyone else is running into the same issue from the command line.

I have a same problem for days. I found a solution which worked from me on Windows. (I also set environment variables, but don't know whether it's needed.)

Add these lines to build.gradle file:

<pre><code>android {

 jackOptions {

 }
 }
 compileOptions {

Replace the old JDK path with your new jdk path.

I was also running into the same issue from the command line on my Windows, it shows the same hint.

<pre><code>Error:Execution failed for task ':app:compileDebugJavaWithJavac'. `compileSdkVersion 'android-24' requires JDK 1.8 or later to compile.`
</code></pre>

check <code>JDK location</code> in <code>Project Structure</code>.

<blockquote>
 In Android Studio open: <code>File</code> > <code>Project Structure</code> > see if JDK location
 points to your JDK 1.8 directory.
</blockquote>

It should look like

<pre><code>JDK Location
C:\Program Files\Java\jdk1.8.0_91
</code></pre>

I already set the correct location to JDK.

check the java version

<pre><code>D:\AndroidSelfTrainingProject\CustomBuildIdDemo&gt;java -version
java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)
</code></pre>

check the gradle version

<pre><code>.D:\AndroidSelfTrainingProject\CustomBuildIdDemo&gt;gradle -v

Groovy: 2.4.4
Ant: Apache Ant(TM) version 1.9.3 compiled on December 23 2013
JVM: 1.7.0_79 (Oracle Corporation 24.79-b02)
OS: Windows 7 6.1 amd64
</code></pre>

JVM version should be 1.8.
To fix it, we can add in the gradle.property
In <code>gradle.properties</code> in the <code>.gradle</code> directory in your <code>HOME_DIRECTORY</code> set <code>org.gradle.java.home=/path_to_jdk_directory</code>. As for me, it is like:

<pre><code>org.gradle.java.home=C:/Program Files/Java/jdk1.8.0_91
</code></pre>

To verify if it is set right, we can make a <code>gradle build</code> task.

<pre><code>D:\AndroidSelfTrainingProject\CustomBuildIdDemo&gt;gradle build
To honour the JVM settings for this build a new JVM will be forked. Please consider using the daemon
: https://docs.gradle.org/2.10/userguide/gradle_daemon.html.

To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 910 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB.
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties.
For more information see https://docs.gradle.org/current/userguide/build_environment.html

Just an FYI I had this error with an Ionic project. All the commands came back pointing to the correct JDK and JAVA_HOME was set correctly.

There was an entry in my PATH to JDK 1.7\bin, replacing that with the 1.8\bin fixed it for me.

blocks|key|113232|text|在Windows10上，我首先检查了项目结构，它指向一个旧的1.7+jdk。我关闭了Android+Studio，然后重命名了旧的jdks+(为了保持一致性，还重命名了jre库)，没有使用最新的1.8库。当我重启Android+Studio并尝试构建应用程序时，它要求我提供Java+JDK库，我给出了最新的1.8JDK库的路径。在我的系统上，它是C:\Program+Files\Java\jdk1.8.0_112。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|113233|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

On Windows 10, I first checked Project Structure and it pointed to an old 1.7 jdk. I closed Android Studio then renamed the old jdks (and jre libraries for consistency) leaving the newest 1.8 library alone. When I restarted Android Studio and attempted to build the application it asked me for the Java JDK library and I gave the path to the newest 1.8 JDK library. On my system it was C:\Program Files\Java\jdk1.8.0_112.

I use Android Studio and recently got the error:

<blockquote>
 Error:Execution failed for task ':app:compileDebugJavaWithJavac'.
 compileSdkVersion 'android-24' requires JDK 1.8 or later to compile.
</blockquote>

But I have JDK 1.8 installed already:

<blockquote>
