Maven 3.8.0 编译器 - 编译时出现致命错误:不支持发行版 11
我无法使用Java 11和最新版本的maven-compiler-plugin进行构建。
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>
当我尝试使用 Maven 构建时:

以下是我正在使用的Maven和Java版本:
➜ 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)
Java 11 将自己标识为“10.0.1”是否会导致此问题?如果我修改我的pom.xml那么即使它没有安装Java 10,它也不会生成任何问题。<release>10</release>
➜ ~ /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
我认为这是 Ubuntu 软件包的一个问题:openjdk-11-jdk
➜ ~ sudo apt install openjdk-11-jdk
