Checking and Updating Your Task’s JDK
Statesman by verifying the JDK assigned to your task. Successful IntelliJ Thought, navigate to Record > Task Construction > Task SDK. Corroborate that the chosen SDK aligns with the supposed Java interpretation for your task. If it’s fit to Java 5, you’ll demand to both replace the task to a newer Java interpretation oregon instal and choice a Java 5 JDK (though the erstwhile is mostly beneficial).
To replace the task’s JDK, choice a much new interpretation from the dropdown card successful the Task SDK conception. If the desired JDK isn’t listed, click on “Adhd SDK” and specify the way to your JDK set up. This measure is captious for making certain IntelliJ makes use of the accurate Java situation for compilation and execution.
For illustration, if your task is utilizing Java eight oregon future, you ought to choice a corresponding JDK eight oregon future. Retrieve to click on “Use” and “Fine” to prevention your adjustments. This is akin to telling IntelliJ which toolbox to usage for gathering your task.
Managing Java Variations connected Your Scheme
Aggregate Java installations tin typically pb to disorder and conflicts. Confirming that your scheme’s JAVA_HOME situation adaptable factors to the accurate JDK is important. This adaptable tells IntelliJ and another Java purposes which JDK to usage by default.
You tin cheque the JAVA_HOME adaptable done your scheme’s situation variables settings. If it’s pointing to an outdated oregon incorrect JDK set up, replace it to the desired interpretation. This measure ensures consistency crossed antithetic tasks and avoids possible interpretation clashes.
Deliberation of the JAVA_HOME adaptable arsenic a cosmopolitan signpost directing each Java purposes to the correct JDK. Sustaining a appropriately configured JAVA_HOME is indispensable for a unchangeable improvement situation.
Resolving Module-Circumstantial JDK Points
Typically, the content mightiness beryllium confined to a circumstantial module inside your task. Successful specified circumstances, you demand to configure the module’s JDK individually. Navigate to Record > Task Construction > Modules. Choice the applicable module and cheque the “Communication Flat” and “Module SDK”.
Guarantee the Module SDK matches the task SDK oregon a suitable interpretation. The Communication Flat ought to correspond to the Java interpretation utilized successful that module. This granular power permits you to negociate antithetic Java variations crossed antithetic modules if your task requires specified flexibility.
For case, if 1 module makes use of Java eight and different makes use of Java eleven, you tin configure all module individually. This is similar assigning antithetic toolboxes for antithetic components of your task.
Maven and Gradle Concerns
If your task makes use of Maven oregon Gradle, guarantee that the Java interpretation outlined successful the respective physique information aligns with your task’s JDK settings successful IntelliJ. Inconsistencies betwixt these configurations tin besides set off the “merchandise interpretation 5 not supported” mistake.
Successful your pom.xml (for Maven) oregon physique.gradle (for Gradle), confirm the Java compiler plugin configuration and the specified origin and mark compatibility variations. These settings ought to lucifer the meant Java interpretation for your task. Updating these physique records-data helps guarantee accordant Java interpretation direction crossed your full task.
Deliberation of your physique records-data arsenic blueprints for your task. Guaranteeing these blueprints specify the accurate Java interpretation is important for seamless compilation and execution.
- Treble-cheque Task SDK configuration.
- Confirm scheme’s JAVA_HOME adaptable.
- Unfastened Task Construction.
- Cheque and Replace Task SDK.
- Corroborate Module Settings.
Troubleshooting this mistake frequently entails a systematic attack of checking these assorted configurations. Larn much astir resolving communal IntelliJ points. By methodically verifying all facet, you tin pinpoint the base origin and instrumentality the due resolution.

Question & Answer :
I’m utilizing IntelliJ Thought Eventual 2019.three.1. Each time I attempt to commencement immoderate elemental Java Maven task (whitethorn it beryllium equal a elemental Hullo Planet) I acquire the pursuing mistake:
Mistake:java: mistake: merchandise interpretation 5 not supported
Moving java --interpretation by terminal I acquire the pursuing output:
openjdk eleven.zero.5 2019-10-15 OpenJDK Runtime Situation (physique eleven.zero.5+10-station-Ubuntu-0ubuntu1.1) OpenJDK sixty four-Spot Server VM (physique eleven.zero.5+10-station-Ubuntu-0ubuntu1.1, combined manner, sharing)
Moving javac --interpretation by terminal I acquire the pursuing output:
javac eleven.zero.5
Going to the Settings of the Java Compiler ( arsenic urged present ) I seat this:
I tried modifying the “Mark bytecode interpretation” to 1.eight however I acquire the pursuing errors:
Mistake:(1, 26) java: bundle javafx.exertion does not be Mistake:(2, 20) java: bundle javafx.phase does not be Mistake:(four, 27) java: can't discovery signal signal: people Exertion Mistake:(12, 23) java: can not discovery signal signal: people Phase determination: people Chief Mistake:(7, 9) java: can not discovery signal signal: methodology motorboat(java.lang.Drawstring[]) determination: people Chief Mistake:(eleven, 5) java: methodology does not override oregon instrumentality a technique from a supertype
Altering it to interpretation 1.eleven I acquire this mistake alternatively:
Mistake:java: Origin action 5 is nary longer supported. Usage 6 oregon future.
What bash you deliberation is the job? However whitethorn I lick it?

Archetypal of each, fit the communication flat/merchandise variations successful pom.xml similar that:
<properties> <maven.compiler.origin>1.eight</maven.compiler.origin> <maven.compiler.mark>1.eight</maven.compiler.mark> </properties>
Maven units the default to 1.5 other. You volition besides demand to see the maven-compiler-plugin if you haven’t already:
<dependency> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <interpretation>three.eight.1</interpretation> </dependency>
Besides, attempt to alteration the Java interpretation successful all of these locations:
Record -> Task construction -> Task -> Task SDK -> eleven.
Record -> Task construction -> Task -> Task communication flat -> eleven.
Record -> Task construction -> Task -> Modules -> -> Sources –> eleven
Successful task -> ctrl + alt + s -> Physique, Execution, Deployment -> Compiler -> Java Compiler -> Task bytecode interpretation -> eleven
Successful task -> ctrl + alt + s -> Physique, Execution, Deployment -> Compiler -> Java Compiler -> Module -> 1.eleven.
