# maven maven-compiler-plugin插件添加premain参数 #

在java程序打包的时候能够在生成的manifest.mf文件中生成一些信息。这些信息能够使用maven的maven maven-compiler-plugin插件直接配置后生成。下面是配置的例子：

<build>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <configuration>
                        <source>1.8</source>
                        <target>1.8</target>
                        <encoding>utf-8</encoding>
                    </configuration>
                </plugin>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-shade-plugin</artifactId>
                    <version>3.0.0</version>
                    <executions>
                        <execution>
                            <phase>package</phase>
                            <goals>
                                <goal>shade</goal>
                            </goals>
                            <configuration>
                                <transformers>
                                    <transformer
                                            implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                        <manifestEntries>
                                            <Main-Class>com.xueyou.dubboagent.App</Main-Class>
                                            <Premain-Class>com.xueyou.dubboagent.App</Premain-Class>
                                        </manifestEntries>
                                    </transformer>
                                </transformers>
                            </configuration>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>

编译后查看MANIFEST.MF文件：

Manifest-Version: 1.0
    Implementation-Title: agent
    Premain-Class: com.xueyou.dubboagent.App
    Implementation-Version: 1.0-SNAPSHOT
    Archiver-Version: Plexus Archiver
    Built-By: wuxueyou
    Specification-Title: agent
    Implementation-Vendor-Id: com.xueyou.dubboagent
    Created-By: Apache Maven
    Build-Jdk: 1.8.0_111
    Specification-Version: 1.0-SNAPSHOT
    Main-Class: com.xueyou.dubboagent.App

能够看到已经把Premain-Class添加到文件中了。
