如何将pom项目打包为runnable jar

Question

我有一个基于免费和开源程序的免费项目：

• 其中一些人拥有pom和公共无障碍罐子
• 其中一些人有pom但没有公共无障碍罐子
• 其中一些人没有pom

我想将项目作为一个独特的jar分发，因为我合法地可以兼容所有许可证，如果有可能用maven生成这样的jar，我不知道如何。你能帮忙吗？

如果不可能分发此类项目的最佳方式是什么？

我的pom由netbeans管理，这是缺少的配置：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <source>1.7</source>
                <target>1.7</target>
            </configuration>
        </plugin>
        <!-- I added the following -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-assembly-plugin</artifactId>
            <configuration>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
                <archive>
                    <manifest>
                        <mainClass>net.hypermove.graphitidb.GraphitiDB</mainClass>
                    </manifest>
                </archive>
            </configuration>
        </plugin>
    </plugins>
</build>

Answer 1

您有很多选择

1. Maven Assembly Plugin与jar-with-dependencies描述符

2. Maven One Jar插件

3. 分发Jar - Zip存档与您的jar，目录lib中的所有依赖项和配置清单，以便于执行。下面的示例配置。

4. Executable Jar与Maven Shade Plugin

5. Runnable Jar，其依赖关系映射到本地maven存储库（可能，但不可移植）Altering The Classpath: Using a Maven Repository-Style Classpath

1。 Jar与依赖性组合

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <executions>
        <execution>
            <id>make-jar-with-dependencies</id>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
            <configuration>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
                <archive>
                    <manifest>
                        <mainClass>eu.codearte.MainClass</mainClass>
                    </manifest>
                </archive>
            </configuration>
        </execution>
    </executions>
</plugin>

2。 Maven One Jar

<plugin>

    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
        <archive>
            <manifest>
                <mainClass>eu.codearte.MainClass</mainClass>
            </manifest>
        </archive>
    </configuration>
</plugin>
<plugin>
    <groupId>org.dstovall</groupId>
    <artifactId>onejar-maven-plugin</artifactId>
    <version>1.4.4</version>
    <executions>
        <execution>
            <goals>
                <goal>one-jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>
...

    <pluginRepository>
        <id>onejar-maven-plugin.googlecode.com</id>
        <url>http://onejar-maven-plugin.googlecode.com/svn/mavenrepo</url>
    </pluginRepository>
</pluginRepositories>

3。分发Jar配置
