Maven Java 构建编译时出错：maven-compiler-plugin

Question

When I try to run as maven build it always give BUILD FAILURE .

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project testJPA: Fatal error compiling: invalid target release: 11 -> [Help 1]

I already tried the following things:

• remove.m2 folder
• reinstall eclipse
• set executable on pom.xml
• set build option to clean

> java -version
java version "1.8.0_261"

> echo %JAVA_HOME%
C:\Program Files\Java\jdk1.8.0_211

---

pom.xml

<plugin>
    <inherited>true</inherited>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.0</version>
    <configuration>
        <source>11</source>
        <target>11</target>
        <encoding>UTF-8</encoding>
        <showWarnings>true</showWarnings>
        <showDeprecation>true</showDeprecation>
    </configuration>
</plugin>

None of them worked. Any guesses?

I managed to find a solution.

I installed JDK 11 and set it at Window > Preferences > Java > Installed JREs > Add > jdk-11.0.9
