The message typically entails that your JAVA_HOME environment variable points to a different Java version.
Here are the steps to follow:
<ul>
<li>Close IntelliJ IDEA</li>
<li>Open a terminal window and check your JAVA_HOME variable value:
<ul>
<li>*nix system: <code>echo $JAVA_HOME</code></li>
<li>Windows system: <code>echo %JAVA_HOME%</code></li>
</ul>
</li>
<li>The JAVA_HOME path should be pointing to a different path, then set it to the openjdk-17 path:
<ul>
<li>*nix system: <code>export JAVA_HOME=/path/to/openjdk-17</code></li>
<li>Windows system: <code>set JAVA_HOME=path\to\openjdk-17</code></li>
</ul>
</li>
<li>Open your project again in IntelliJ IDEA</li>
<li>Make sure to set both source and target compatibility versions (not only the <code>sourceCompatibility</code>)</li>
</ul>
You should be able to build your project.
<h2>EDIT: Gradle Toolchain</h2>
You may need also to instruct Gradle to use a different JVM than the one it uses itself by setting the Java plugin toolchain to your target version:
<pre><code>// build.gradle
java {
 toolchain {
 languageVersion = JavaLanguageVersion.of(17)
 }
}
</code></pre>

If you start your project from a main method directly invoked from Intelij then the missing dialog execution configurations may be the cause of the error.
Always check the execution configurations to make sure the correct JRE folder is plugged in. In latest versions of jdk there is not a specific jre folder but the complete jdk package, so make sure it points at this folder.

I was running into this issue, only when building from terminal, while the execution from the IntelliJ Run Configuration works
The reason is probably, that I had downloaded the JDK from the relatively new way of doing it directly from the IDE
<a href="https://i.stack.imgur.com/GrsXo.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/GrsXo.png" alt="enter image description here" /></a>
My guess is, that this JDK with its path that is set here
<a href="https://i.stack.imgur.com/btVvN.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/btVvN.png" alt="enter image description here" /></a>
Is only known to IntelliJ and likely dynamically passed to Gradle when running a run configuration, and not known to Gradle itself.
I tried to figure out what is happening, so I've added this task which in both cases prints the same path to an older local JDK.
<pre><code>tasks.build.doFirst {
 println &quot;used jdk path: &quot; + System.getenv('JAVA_HOME')
}
</code></pre>
<blockquote>
C:\Program
Files\GraalVM\graalvm-ce-java11-21.1.0
</blockquote>
Afterwards I've deleted the old JDK under that path and retried both, run configuration and terminal execution. Now the run configuration still works, while printing the same invalid JDK path, and the terminal execution fails with
<blockquote>
ERROR: JAVA_HOME is set to an invalid directory: C:\Program
Files\GraalVM\graalvm-ce-java11-21.1.0
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.
</blockquote>
I had expected the error in both cases, but it seems the JAVA_HOME directory is not necessarily used and in some way other than with the env variable, IntelliJ has to tell Gradle to use the right JDK from the .jdks directory.
This is just an assumption, if anyone has an explanation I'd appreciate it, especially how Gradle is able to know what JDK to use.

I've created a new Java project in IntelliJ with Gradle that uses Java 17. When running my app it has the error <code>Cause: error: invalid source release: 17</code>.
My Settings
I've installed <code>openjdk-17</code> through <code>IntelliJ</code> and set it as my <code>Project SDK</code>.
The <code>Project language level</code> has been set to <code>17 - Sealed types, always-strict floating-point semantics</code>.

In <code>Modules -&gt; Sources</code> I've set the <code>Language level</code> to <code>Project default (17 - Sealed types, always strict floating-point semantics)</code>.

In <code>Modules -&gt; Dependencies</code> I've set the <code>Module SDK</code> to <code>Project SDK openjdk-17</code>.

In <code>Settings -&gt; Build, Execution, Deployment -&gt; Compiler -&gt; Java Compiler</code> I've set the <code>Project bytecode version</code> to <code>17</code>.

Gradle
<pre><code>plugins {
 id 'org.springframework.boot' version '2.5.6'
 id 'io.spring.dependency-management' version '1.0.11.RELEASE'
 id 'java'
}

group = 'com.app'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'

repositories {
 mavenCentral()
}

dependencies {
 implementation 'org.springframework.boot:spring-boot-starter-web'
 implementation 'org.springframework.boot:spring-boot-starter-websocket'
 testImplementation 'org.springframework.boot:spring-boot-starter-test'
 implementation 'com.fasterxml.jackson.core:jackson-core:2.13.0'
 implementation 'com.fasterxml.jackson.core:jackson-databind:2.13.0'
}

test {
 useJUnitPlatform()
}
</code></pre>
I've looked at all of the answers <a href="https://stackoverflow.com/questions/46280859/intellij-idea-error-java-invalid-source-release-1-9">here</a> but I can't seem to fix this. I must be missing something but I can't find it. I've not had any problems using Java 8 or 11.
How do I resolve this?
