Question

我有一个使用 4 个 OpenGL jar 和 1 个 dll 的 Java 项目，我收到这些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 git clone 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 安装到项目内的本地存储库中。这样，我只是设置依赖项，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>
      ...

使用 src/assembly.xml 中的 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 jars 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 文件应该位于可执行 jar 附近的目标文件夹中，但即使我手动复制该文件，当我尝试使用 java -jar executable-jar.jar 运行 jar 时，例如，我收到以下错误：

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

我正在使用 intellij 并使用 File -> Project Structure -> Libraries -> 添加了包含 jars 和 dll 的文件夹。当我使用 Intellij 运行/构建项目时，一切正常。

我做错了什么？有没有更好的方法来做到这一点？

我最终从程序集文件中删除了 dll 的依赖项集，并使用 maven-dependency-plugin 复制了 dll 依赖项，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>

发生 ArrayIndexOutOfBoundsException 是因为我使用 jdk 16 而不是 jdk 12 来运行 jar。希望这对其他人有帮助。

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，但一开始我并不知道该怎么做。

只需将 --illegal-access=permit 添加到 VM-Options。在我的示例中，它与 OpenJDK-15 一起开箱即用，但在使用 OpenJDK-16 时我必须添加该 VM-Option。

我在使用 Jogamp 2.3.2 时遇到了同样的异常，在 Jogamp 2.4.0 中相同的修补程序有所帮助，但异常更改为：

Exception in thread "AWT-EventQueue-0" com.jogamp.opengl.GLException: Unable to determine GraphicsConfiguration: WindowsWGLGraphicsConfiguration[DefaultGraphicsScreen[WindowsGraphicsDevice[type .windows, connection decon, unitID 0, handle 0x0, owner false, NullToolkitLock[obj 0x1dc258d9]], idx 0], pfdID 7, ARB-Choosen true,
