问题描述

我刚刚尝试使用maven-release-plugin发行与Java 9兼容的项目.但是，它在maven-compiler-plugin中以

I just tried to release my Java 9 compatible project with maven-release-plugin. However, it failed in maven-compiler-plugin with

无法执行目标 org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (默认编译)在项目电子邮件上:致命错误编译:无效 目标版本:9

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project email: Fatal error compiling: invalid target release: 9

有趣的是，如果我独立运行maven-compiler-plugin，它可以正常工作. 我的设置:

Funny thing is that maven-compiler-plugin works fine in case I run it standalone. My setup:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.7.0</version>
            <configuration>
                <source>9</source>
                <target>9</target>
            </configuration>
        </plugin>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-release-plugin</artifactId>
            <version>2.5.3</version>
            <configuration>
                <autoVersionSubmodules>true</autoVersionSubmodules>
                <tagNameFormat>v@{project.version}</tagNameFormat>
            </configuration>
        </plugin>

Maven版本3.5.0.

Maven version 3.5.0.

mvn clean install正常；

mvn release:prepare release:perform -DignoreSnapshots=true失败，发生以上异常.

mvn release:prepare release:perform -DignoreSnapshots=true fails with above exception.

调试输出:

推荐答案

根据最近更新的Java + 9 +-+拼图，maven-release-plugin中不需要或不需要更改以与JDK9兼容.

According to the Java+9+-+Jigsaw which was updated very recently there is no change required or desired in the maven-release-plugin to be compatible with JDK9.

另外，从该问题共享的日志中，您的情况下的输出似乎是由于配置错误的Maven以及 Java版本小于9 .

Additionally from the logs shared in the question the output in your case seems to be because of a misconfigured Maven with Java version less than 9.

虽然我遇到了类似的问题，但我注意到Maven在使用sudo执行时和通常在命令提示符下使用的Java版本是不同的.

While I was facing a similar issue, I had noticed that the java version used by Maven when executed using sudo and normally on command prompt were different.

要坚持使用maven使用的Java的一致版本，请确保已配置mavenrc.您可以通过类似的方式来做到这一点:

To stick to consistent version of java used by maven make sure you have a mavenrc configured. You can do that in a similar way to this:

vi ~/.mavenrc

，然后将其与以下内容一起保存:

and then save it with content as follows:

export PATH
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home
export PATH=${PATH}:$JAVA_HOME/bin

执行

Execute 

mvn -version

，并通过命令提示符和 intelliJ终端确保其输出是一致的.
