mvn -Pandroid gluonfx:构建无法定位Graalvm安装目录

Question

我希望这不是一个与滥用环境变量有关的简单错误！

编辑:是的，就是这样发生的。我想我可以删除整个问题，以免妨碍其他胶子/Graavlm问题的主题。

用于创建Android构建的胶子文档让我们执行以下命令：

mvn -Pandroid gluonfx:build

我是在我的Ubuntu20.04系统上执行这一操作的，该系统是从文档中引用的下载的"HelloFX“项目中执行的。

控制台输出还有更多内容。如有要求，我会把这个包括在内。

我认为这里的关键是：

找不到org.apache.maven.plugin.MojoExecutionException: GraalVM安装目录。将GRAALVM_HOME设置为环境变量或将graalvmHome设置为gluonfx-plugin配置。

下面是GRAALVM_HOME引用的文件夹中文件的列表。这些是从胶子文档中列出的Graalvm版本中解压出来的。

phil@UbuntuDesktop:~/Projects/metronome/gluon-samples-master/HelloFX$ cd $GRAALVM_HOME

可能出什么问题了？也许环境变量被“gluonfx-plugin配置中的graalvmHome”覆盖了？这不是指项目的pom.xlm吗？在android的相关maven配置文件中，我没有看到任何东西。

        <plugin>
            <groupId>com.gluonhq</groupId>
            <artifactId>gluonfx-maven-plugin</artifactId>
            <version>${gluonfx.maven.plugin.version}</version>
            <configuration>
                 <target>${gluonfx.target}</target>
                 <mainClass>${main.class}</mainClass>
            </configuration>
        </plugin>

从简介中：

    <profile>
        <id>android</id>
        <properties>
            <gluonfx.target>android</gluonfx.target>
        </properties>
    </profile>

在这一过程中，可能会有更多的问题。我担心文档中提到了安卓和谷歌安装m2Repositories的“附加”要求，但据我所知，我最近安装的Android并没有在SDK，SDK工具中提供这些。

Answer 1

@Jose发现的答案:使用sudo使我们脱离了声明环境变量的用户环境。

Answer 2

下载=> https://github.com/graalvm/graalvm-ce-builds/releases/tag/vm-22.1.0并在系统名为GRAALVM_HOME和path中创建新的环境变量.
