使用Moditect为现有的Maven依赖项添加module-info。

javamavenjlinkmoditect
6
我正在使用JavaFX，并且有一些依赖项不是自动模块。当尝试运行mvn clean javafx:jlink时，我收到以下错误提示：
Error: automatic module cannot be used with jlink: org.apache.commons.io from [...]`

这也对org.apache.commons.commons-lang3和commons-codec.commons-codec出现了错误。我看到的错误是随机的。
所以我研究了使用jdeps来为依赖项生成模块信息，例如。
jdeps --generate-module-info tmp .../.m2/repository/commons-io/commons-io/2.12.0/commons-io-2.12.0.jar

然后我使用Moditect将module-info添加到现有的jar包中。

但是我仍然遇到相同的错误。
我的模块信息：
module uk.co.conoregan.showrenamer {

首先，为什么要使用插件作为依赖？其次，为什么将模块的输出定义为modules，因为通常的modul-info.class必须位于jar/root-location中...? - undefined
还从依赖项中移除了其他插件，并更新了我的问题。 - Conor Egan
你能展示一下jlink的配置吗？它是否使用${project.build.directory}/modules？ - undefined
@dan1st 你可以提供的选项可以在这里找到：https://github.com/openjfx/javafx-maven-plugin#javafxjlink-options。我有maven配置，但没有可选的选项。我不确定你的意思是什么？ - undefined

问题
- JLink无法与自动模块（即没有module-info.java文件的包）一起使用。
步骤
- 使用maven-dependency-plugin将依赖项复制到{build_folder}/dependency。
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <version>3.6.0</version>
    <executions>
        <execution>
            <id>copy</id>
            <phase>package</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>
        </execution>
    </executions>
</plugin>

使用moditect-maven-plugin为自动模块添加module-info。
<plugin>
    <groupId>org.moditect</groupId>
    <artifactId>moditect-maven-plugin</artifactId>
    <version>1.0.0.Final</version>
    <executions>
        <execution>
            <id>add-module-infos</id>
            <phase>generate-resources</phase>
            <goals>
                <goal>add-module-info</goal>

            <configuration>
                <outputDirectory>

                        <moduleInfoSource>
                            module org.apache.commons.io {
                            exports org.apache.commons.io;
                            exports org.apache.commons.io.build;
                            exports org.apache.commons.io.charset;
                            exports org.apache.commons.io.comparator;
                            exports org.apache.commons.io.file;
                            exports org.apache.commons.io.file.attribute;
                            exports org.apache.commons.io.file.spi;
                            exports org.apache.commons.io.filefilter;
                            exports org.apache.commons.io.function;
                            exports org.apache.commons.io.input;
                            exports org.apache.commons.io.input.buffer;
                            exports org.apache.commons.io.monitor;
                            exports org.apache.commons.io.output;
                            exports org.apache.commons.io.serialization;

                            }

                        </moduleInfoSource>
                    </module>
                </modules>
                <overwriteExistingFiles>true</overwriteExistingFiles>
            </configuration>
        </execution>

    </executions>
</plugin>

如何获取<moduleInfoSource>内容？
  • 进入包含所需（依赖）.jar文件的文件夹
  • 如果您使用Intellij IDEA，在项目视图中，有一个名为External Libraries的部分。双击条目，在.jar上右键单击，选择打开方式 ->资源管理器。
  • 在该文件夹中打开命令提示符
  • jdeps -generate-module-info . {jar_file_name}.jar
  • 确保PATH环境变量设置正确
  • 用文本编辑器打开生成的module-info.java文件并复制内容
  • 粘贴到<moduleInfoSource>部分

创建运行时镜像（使用jlink，在后端）

  • 请根据您的项目信息更改<modules>和<launcher>部分。
  • 如果您的模块是非模块化的，重要的是主类不直接扩展javafx.Application。我们可以创建一个看起来像这样的启动器类（参考待定）：

launcher class

public class Launcher {  
    public static void main(String[] args) {  
        HelloApplication.main(args);  
    }  
}

pom.xml

<execution>
    <id>create-runtime-image</id>
    <phase>package</phase>
    <goals>
        <goal>create-runtime-image</goal>
    </goals>
    <configuration>
        <jarInclusionPolicy>APP_WITH_DEPENDENCIES</jarInclusionPolicy>
        <modulePath>
            <path>${project.build.directory}/${project.artifactId}-${project.version}.${project.packaging}</path>
            <path>${project.build.directory}/dependency</path>
        </modulePath>
        <modules>
            <module>com.example.soone</module>
        </modules>
        <launcher>
            <name>hello</name>
            <module>com.example.soone/com.example.soone.Launcher</module>
        </launcher>
        <outputDirectory>
            ${project.build.directory}/jlink-image
        </outputDirectory>
    </configuration>
</execution>

建议

  • 我建议将构建系统更改为Gradle，它与自动模块更好地配合，您不必手动解决依赖关系，尤其是在使用JavaFX时，这将节省很多时间。
谢谢您的回复。如果您正在使用module-info.java，那么您就不需要一个不继承Application的主类。您提供的最后一个执行步骤应该放在哪里？为什么切换到Gradle会让使用自动模块更容易？ - undefined

在执行moditect插件时，请参考项目链接中的pom.xml。在Gradle中，它支持自动模块。您不必使用jdeps来找出module-info.java，这在某些情况下效果不佳，并且在较大的第三方依赖项（如Spring框架的某些库）中需要更多的工作。 - undefined
谢谢提供的信息，我想尝试使用Maven来使其工作，但如果失败的话，我会尝试迁移到Gradle。提供的项目链接无效，请您能否编辑您的回答？ - undefined

抱歉回复晚了，我已经更新了链接。 - undefined

所谓的“模块化的jar”意味着它已经被模块化，并且具有module-info.java，不需要在Moditect中进行额外的设置。但是据我所记，使用jackson-databind可能会遇到一些多版本的问题，这是另一个话题了。很高兴你在Gradle上没有遇到问题 :) - undefined
