I am using eclipse as IDE. When I right click on the project and then click maven update my java version change to 1.5. Here is what I did so far, I followed all the steps listed here

- I changed "Java build path" to "workspace default jre 1.8.0_25"
- Then changed "java compiler" to 1.8
- Then changed "project facets">java>1.8
- Changed pom.xml java version to 1.8
<build>
<plugins>
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>9.1.3.v20140225</version>
</plugin>
<plugin>
<groupId>org.apache.maven.plugin</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
After all this when I click on "Maven update" my java version change to 1.5 automatically. Also in above steps, first two step's version also change to 1.5 automatically. How can I fix this?
Solution
Open your pom.xml
file and add the following lines on it:
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
Where 1.8
is the Java version of your current JDK/JRE. Another way of doing this is adding a <build>
with the maven-compile-plugin
as:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.2</version> <!-- or whatever current version -->
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
If you are looking for a way to make it work with Java versions 9+ please take a look at @JDelorean's answer.
