无法从 payara-micro-maven-plugin 启动 Payara Micro，获取 "unsupported JDK"

Question

我整理了一个示例项目来演示我遇到的问题。

https://github.com/johnmanko/payara-micro-plugin-group

基本上，我在开发期间尝试通过 payara micro 的 maven 插件启动我的应用程序。这是 pom.xml 配置：

<plugin>
                <groupId>fish.payara.maven.plugins</groupId>
                <artifactId>payara-micro-maven-plugin</artifactId>
                <version>1.4.0</version>
                <configuration>
                    <useUberJar>false</useUberJar>
                    <contextRoot>/myapp</contextRoot>
                    <payaraVersion>${version.payara}</payaraVersion>
                    <deployWar>false</deployWar>
                    <artifactItem>
                        <groupId>fish.payara.extras</groupId>
                        <artifactId>payara-micro</artifactId>
                        <version>${version.payara.micro}</version>
                    </artifactItem>
                    <javaCommandLineOptions>
                        <option>
                            <value>-Xdebug</value>
                        </option>
                    </javaCommandLineOptions>
                    <commandLineOptions>
                        <option>
                            <key>--autoBindHttp</key>
                        </option>
                        <option>
                            <key>--nocluster</key>
                        </option>
                        <option>
                            <key>--port</key>
                            <value>8095</value>
                        </option>
                        <option>
                            <key>--prebootcommandfile</key>
                            <value>${project.basedir}/src/main/resources/pre-boot-commands.txt</value>
                        </option>
                        <option>
                            <key>--postbootcommandfile</key>
                            <value>${project.basedir}/src/main/resources/post-boot-commands.txt</value>
                        </option>
                        <option>
                            <key>--deploy</key>
                            <value>${project.build.directory}/${project.build.finalName}</value>
                        </option>
                    </commandLineOptions>
                </configuration>
            </plugin>

结果如下：

该项目是用 JDK 1.8 构建的，maven 是通过将 JAVA_HOME 设置为 JDK 1.8:

来启动的

DATABASE_USER=user \
DATABASE_PASS=password \
DATABASE_NAME=MY_DB_NAME \
DATABASE_SERVER=localhost \
DATABASE_SERVER_PORT=1234 \
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64 \
M2_HOME=/usr/share/maven \
/usr/share/maven/bin/mvn payara-micro:start

系统默认值是 Java 18，但我什至看不出这有什么用。所有包含的应用程序依赖项都是使用 JDK 1.8 或更早版本编译的（我检查了每一个）。

为什么它会选择主要版本 62？

我找到了原因。该插件使用 Apache Toolchain 来定位 java，它找到了错误的（即系统的）。

一种解决方案是添加插件 <javaPath> 选项：

                <configuration>
                    <useUberJar>false</useUberJar>
                    <contextRoot>/myapp</contextRoot>
                    <payaraVersion>${version.payara}</payaraVersion>
                    <deployWar>false</deployWar>                    
                    <javaPath>/usr/lib/jvm/java-1.8.0-openjdk-amd64/jre/bin/java</javaPath>

当然，这不适用于其他系统上的开发人员，例如 Mac 的 Windows。

正确的方法是配置一个 ~/.m2/toolchains.xml 文件并在 pom 中设置 Toolchain 以使用它。

~/.m2/toolchains.xml:

<?xml version="1.0" encoding="UTF-8"?>

    <!-- JDK toolchains -->

        </provides>
        <configuration>
            <jdkHome>/usr/lib/jvm/java-1.8.0-openjdk-amd64</jdkHome>
        </configuration>

使用 nbactions.xml 启动：

            <Env.DATABASE_SERVER_PORT>1234</Env.DATABASE_SERVER_PORT>
        </properties>
    </action>
</actions>

使用命令行启动：

DATABASE_USER=user \
DATABASE_PASS=password \
DATABASE_NAME=MY_DB_NAME \
DATABASE_SERVER=localhost \
DATABASE_SERVER_PORT=1234 \
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64 \

/usr/share/maven/bin/mvn toolchains:toolchain payara-micro:start
