Maven: Invalid target release: 10
JavaMavenpom.xmlJava 10Java Problem Overview
I'm trying to compile my maven
project using Java 10
but I'm having trouble. In my IDE (IntelliJ IDEA
) everything compiles and runs just fine under Java 10
. I installed the latest maven
version 3.5.4
and pointed my JAVA_HOME
to the JDK 10
:
$ mvn --version
Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-17T20:33:14+02:00)
Maven home: C:\Maven\bin\..
Java version: 10.0.2, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jdk-10.0.2
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"
The maven
command I use is:
mvn package -Dmaven.test.skip
In my pom.xml
I had the following for Java 8
which worked fine:
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<libraries.directory>libraries</libraries.directory>
</properties>
For Java 10
I changed it to the following:
<maven.compiler.source>10</maven.compiler.source>
<maven.compiler.target>10</maven.compiler.target>
This does not work, just like using 1.10
as the version for the source and target compiler.
The full debug logging output (-X
command line switch) is the following:

Adding the maven-compiler-plugin
like suggested in this answer also does not work:
Fatal error compiling: invalid flag: --release -> [Help 1]
Any ideas on how to fix this problem?
Java Solutions
Solution 1 - Java
Same problem fixed for me by setting JAVA_HOME environment variable to point to the JDK with right version.
My source and destination java version in maven-compiler-plugin were 11, java -version
was also on version 11, but my JAVA_HOME was pointing to JDK-1.8.
Check JAVA_HOME again by using a terminal instead of IDE:
Linux:
echo $JAVA_HOME
Win:
echo %JAVA_HOME%
Then Build your project in the same terminal:
mvn clean package
Solution 2 - Java
This worked for me:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.7.0</version>
<configuration>
<release>10</release>
</configuration>
</plugin>
</plugins>
</build>
This answer says you need:
<dependencies>
<dependency>
<groupId>org.ow2.asm</groupId>
<artifactId>asm</artifactId>
<version>6.2</version> <!-- Use newer version of ASM -->
</dependency>
</dependencies>
inside the <plugin/>
tag, but the newer mvn (3.5.4) must obviate that, since I didn't need it.
Solution 3 - Java
Get your java version by running java -version
.
You'll get a output like :
java version "1.8.0_201"
Now go to your POM file and update source and target properities of maven-compiler-plugin
with your installed java version. In my case it's 1.8
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
Solution 4 - Java
I had a similar problem with spring boot and java 11. I solved it by defining the following property in my pom
<maven.compiler.release>11</maven.compiler.release>
Might be useful for someone in the future.
Solution 5 - Java
This means you are using java.version 10 which you have not installed.
<properties>
<java.version>10</java.version>
</properties>
Solution 6 - Java
As you are using Intellij, you need to follow below steps (Here I'm using Java 11, but the same applies to Java 10 and other versions as well)-
- Change SDK under Project Structure to Java 11
- Change language level for modules (if needed) under Project Structure
- Change JRE under runner in settings
- Change Target bytecode version under Java compiler in Settings
-
Check maven version under Maven in settings for supporting Java 11
-
In your pom, mention the version as follows, you can ignore the encoding tag here
- Lastly confirm your run configuration before building project
- If you are using Windows machine, then change environment variables JAVA_HOME, Path and MAVEN_HOME accordingly.
Solution 7 - Java
Check your JAVA_HOME version. It seems your java version in JAVA_HOME and in POM is different. Set JAVA_HOME path properly by editing in Environment variable in Windows.
Solution 8 - Java
Sometimes it's just your java version. For example, when the project uses Java 10 but your Java Path is set to 8, etc. Try running java -version
and make sure it's the same as your project. If not, fix it and try again.
Solution 9 - Java
thanks to the answer above, You are using 10, i use 11, but i guess the steps are similar.
the whole point for me is to explicitly specify the version as java 11 in my pom.xml, and I solved the problem by taking the following steps.
-
open terminal and input: java -version, then i got 1.8, and i went to .bash_profile to switch the java version to 11.2 as i have multiple java version installed. please remember "restart" your terminal and check your java version again to confirm switch is successful.
-
Then i went to File -> Project Structure to make sure my IntelliJ using the same version as my env, which is 11.2.
-
RESTART your Intellij, mvn clean install, solved, hope this could help someone with this issue, thanks.
Solution 10 - Java
In "File >> Project Structure >> Project Settings >> Project >> Project SDK" choose the version of your Java installed and click OK.
It solved my Maven problem:
> Invalid Target Release: 16 .
