java如何将pom项目打包为可运行jar

Question

我有一个完全基于免费开源程序的免费项目：

• 其中一些有pom和可供公众使用的罐子
• 其中一些有pom，但没有可供公众使用的罐子
• 其中一些没有pom

我想把这个项目作为一个独特的jar分发，因为所有的许可证都是兼容的，我可以合法地分发，如果有可能用maven生成这样一个jar，我不知道如何生成。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，下面是缺少的配置：

<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

你有很多选择

1. 带有jar-with-dependencies描述符的Maven Assembly Plugin

2. Maven One Jar插件

3. Distribution Jar-Zip存档与您的Jar、目录库中的所有依赖项和配置的清单，以便于执行。下面是配置示例

4. Executable Jar与Maven Shade Plugin

5. 具有映射到本地maven存储库的依赖项的可运行Jar（可能，但不可移植）Altering The Classpath: Using a Maven Repository-Style Classpath

一,。用依赖项组装的Jar

<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>

二,。Maven一罐

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

三,。分发Jar配置

            <phase>package</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.build.directory}/lib</outputDirectory>
                <overWriteReleases>true</overWriteReleases>
                <overWriteSnapshots>true</overWriteSnapshots>
                <overWriteIfNewer>true</overWriteIfNewer>
                <stripVersion>false</stripVersion>
                <stripClassifier>false</stripClassifier>

            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>

                <descriptors>
                    <descriptor>src/main/assembly/bundle.xml</descriptor>
                </descriptors>
