Я не могу построить с использованием Java 11 с последней версией плагина maven-compiler.
pom.xml:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<release>11</release>
</configuration>
</plugin>
<plugins>
<build>
когда я пытаюсь построить с помощью Maven:

Ниже приведены версии Maven и Java, которые я использую:
➜ mvn -version
Apache Maven 3.5.2
Maven home: /usr/share/maven
Java version: 10.0.1, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-11-openjdk-amd64
Default locale: en_GB, platform encoding: UTF-8
OS name: "linux", version: "4.15.0-29-generic", arch: "amd64", family: "unix"
➜ /usr/lib/jvm/java-11-openjdk-amd64/bin/java -version
openjdk version "10.0.1" 2018-04-17
OpenJDK Runtime Environment (build 10.0.1+10-Ubuntu-3ubuntu1)
OpenJDK 64-Bit Server VM (build 10.0.1+10-Ubuntu-3ubuntu1, mixed mode)
Может ли Java 11 идентифицировать себя как "10.0.1", чтобы вызвать проблему? Если я изменю свой pom.xml на <release>10</release>
тогда он будет создан без проблем, даже если у меня нет Java 10.
➜ ~ /usr/lib/jvm/java-11-openjdk-amd64/bin/javac -version
javac 10.0.1
➜ javac --release 11 SomeClass.java
javac: release version 11 not
supported Usage: javac <options> <source files>
use --help for a list of possible options
Я думаю, что это проблема с openjdk-11-jdk
Ubuntu openjdk-11-jdk
:
➜ ~ sudo apt install openjdk-11-jdk
