maven生成jar之后，无法检测到包

[Azalea]

默认打包的 jar 里面就只有你写的东西呀w
大概有两种方式解决啦w

1. Shade - 把所有导入的包混在你的 jar 里面w
   这样的好处是方便, 一个 jar 就能运行.
2. Copy-dependencies - 把所有导入的包单独导出w
   这样的好处是如果要经常更新的话, 上传的 jar 可以很小, 但是有点麻烦.

Shade 的例子:

<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <version>2.5</version>
        <configuration>
            <archive>
                <manifestEntries>
                    <Main-Class>org.hydev.something.Main</Main-Class>
                </manifestEntries>
            </archive>
        </configuration>
    </plugin>

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>2.4.1</version>
        <executions>
            <execution>
                <phase>package</phase>
                <goals>
                    <goal>shade</goal>
                </goals>
            </execution>
        </executions>
        <configuration>
            <shadedArtifactAttached>true</shadedArtifactAttached>
            <createDependencyReducedPom>false</createDependencyReducedPom>
        </configuration>
    </plugin>
</plugins>

Copy-dependencies 的例子:

<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <executions>
            <execution>
                <id>copy-dependencies</id>
                <phase>prepare-package</phase>
                <goals>
                    <goal>copy-dependencies</goal>
                </goals>
                <configuration>
                    <outputDirectory>${project.build.directory}/libs</outputDirectory>
                    <overWriteIfNewer>true</overWriteIfNewer>
                </configuration>
            </execution>
        </executions>
    </plugin>

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <version>2.5</version>
        <configuration>
            <archive>
                <manifestEntries>
                    <Main-Class>org.hydev.something.Main</Main-Class>
                </manifestEntries>
            </archive>
        </configuration>
    </plugin>
</plugins>

Copy-dependencies 方式的启动脚本:

java -cp "YourJar.jar:./libs/*" sample.package.Main

明白了，我对maven打包的使用挺不熟的

现在还有一个问题啊

看上去貌似是jdk内部解析json的问题

这个问题在win系统中没问题，但是在ubuntu上跑有问题。运行方式是采用jar

[Azalea]

报了 Json 语法错误哇w
是端口连不上的问题吧...
因为添加账号的时候会自动测试连接呀w
测试连接如果返回的不是 JSON 的话就会这样报错啦w

[GuohaoLi]

是的，刚刚我又重新测试了，应该是docker的端口配置问题
