使用maven的具有依赖项和dll依赖项的可执行jar

Question

我有一个使用4个OpenGL jar和1个dll的Java项目，我收到了这个项目作为计算机图形学课程的项目。我想让maven为我构建一个可执行的jar，这样我就可以从另一台计算机上git克隆我的repo，并使用maven构建它来执行。(最好使用maven clean install(

到目前为止我做了什么：

• 将4个jar和dll安装到项目内部的本地存储库中。通过这种方式，我只是设置依赖项，并且文件是从git repo复制的，例如：

  <repositories>
  <repository>
  <id>local-maven-repo</id>
  <url>file:///${project.basedir}/local-maven-repo</url>
  </repository>
  </repositories>
  <dependencies>
  <dependency>
  <groupId>com.computer.graphics</groupId>
  <artifactId>jogl</artifactId>
  <version>1.0</version>
  </dependency>
  <dependency>
  <groupId>com.computer.graphics</groupId>
  <artifactId>gluegenrt</artifactId>
  <version>1.0</version>
  <scope>runtime</scope>
  <type>dll</type>
  </dependency>
  ...
  

• 在src/assembly.xml:中使用assembly.xml设置maven程序集插件

  <plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-assembly-plugin</artifactId>
  <configuration>
  <!--        Configure a class for executable jar        -->
  <archive>
  <manifest>
  <mainClass>Main class</mainClass>
  </manifest>
  </archive>
  <!--          Points to the assembly descriptor to use          -->
  <descriptors>
  <descriptor>src/assembly.xml</descriptor>
  </descriptors>
  </configuration>
  <!--        Bind goal assembly:single into build process        -->
  <executions>
  <execution>
  <id>make-assembly</id> <!-- this is used for inheritance merges -->
  <phase>package</phase> <!-- bind to the packaging phase -->
  <goals>
  <goal>single</goal>
  </goals>
  </execution>
  </executions>
  </plugin>
  

• 尝试将jar和dll包含到可执行jar中：

<assembly xmlns="http://maven.apache.org/ASSEMBLY/2.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/ASSEMBLY/2.1.0 http://maven.apache.org/xsd/assembly-2.1.0.xsd">
<id>graphics-assembly</id>
<formats>
<format>jar</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
<dependencySet>
<outputDirectory>/</outputDirectory>
<useProjectArtifact>true</useProjectArtifact>
<scope>runtime</scope>
<unpack>true</unpack>
<includes>
<include>*:jar:*</include>
</includes>
</dependencySet>
<dependencySet>
<outputDirectory>/</outputDirectory>
<includes>
<include>*:dll*</include>
</includes>
</dependencySet>
</dependencySets>
</assembly>

据我所知，dll文件应该在可执行jar附近的目标文件夹中，但即使我手动复制了该文件，例如，当我尝试使用java -jar executable-jar.jar运行jar时，我得到以下错误：

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 1

• 我正在使用intellij，并简单地使用File->链接文件；项目结构->库->添加了包含jar和dll的文件夹。当我使用intellij运行/构建项目时，一切都正常

我做错了什么？有更好的方法吗？

Answer 1

我最终从程序集文件中删除了dll的dependencySet，并使用maven依赖插件复制dll依赖，如下所示：

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.1.2</version>
<executions>
<execution>
<id>copy</id>
<phase>package</phase>
<goals>
<goal>copy</goal>
</goals>
</execution>
</executions>
<configuration>
<artifactItems>
<artifactItem>
<groupId>com.computer.graphics</groupId>
<artifactId>gluegenrt</artifactId>
<version>1.0</version>
<type>dll</type>
<outputDirectory>${project.build.directory}</outputDirectory>
<destFileName>gluegen-rt.dll</destFileName>
</artifactItem>
</artifactItems>
</configuration>
</plugin>

ArrayIndexOutOfBoundsException发生，因为我使用的是jdk 16而不是jdk 12来运行jar。希望这能帮助其他人。

Answer 2

我最近遇到了同样的问题。这似乎是jogl/jogamp中的一些已知错误，但一开始我并不清楚该怎么办。

只需将--illegal-access=permit添加到VM选项中即可。在我的示例中，它在OpenJDK-15中开箱即用，但在使用OpenJDK-16时，我不得不添加VM选项。

我在使用Jogamp 2.3.2时遇到了同样的异常，在Jogamp 2.4.0中，同样的修补程序也有帮助，但异常变为：
