只在Maven中创建可执行的jar-with-dependencies

提问于
浏览 次

在我的 pom.xml 中，我使用maven-assembly-plugin在运行"mvn clean install"时创建一个可执行的jar-with-dependencies . 现在它首先创建非可执行文件"name-version.jar"，之后创建"name-version-jar-with-dependencies.jar" .

我可以以某种方式配置 pom.xml ，以便它不会创建不可执行的JAR文件吗？

目前我使用<appendAssemblyId> false </ appendAssemblyId>所以它只是覆盖了第一个文件......

此外，我得到了几个“...已添加，跳过”消息 . 我可以以某种方式阻止他们吗？

这是我的 pom.xml 中的maven-assembly-plugin定义：

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.2-beta-5</version>
    <configuration>
        <appendAssemblyId>false</appendAssemblyId>
        <archive>
            <manifest>
                <mainClass>my.main.class</mainClass>
            </manifest>
        </archive>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
    </configuration>
    <executions>
        <execution>
            <id>make-assembly</id>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
</plugin>
maven jar

    我想我已经弄清楚如何做到这一点 . 您必须离开jar，否则您将丢失编译器和资源复制，以及构建您需要的jar所需的所有其他内容 .

    我的解决方案基本上涉及欺骗maven，所以我想要提防的是，很可能在将来的版本中这不会起作用......

    <build>
    <defaultGoal>install</defaultGoal>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
            </configuration>
        </plugin>
        <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <configuration>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
                <finalName>dumpster-diver</finalName>
                <appendAssemblyId>false</appendAssemblyId>
                <archive>
                    <manifest>
                        <mainClass>DumpsterDiver</mainClass>
                    </manifest>
                </archive>
            </configuration>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
    <finalName>${project.artifactId}</finalName>
</build>

    请注意，在列出的构建配置中，maven-assembly-plugin和构建本身的finalName匹配 . 另请注意 <appendAssemblyId>false</appendAssemblyId> . 如果这样做，构建和程序集jar的输出文件名将完全匹配 . Maven肯定会警告你，但是会把你想要的jar放在你的目标目录和你的本地存储库中 .

    以下是此项目中“mvn clean install”的输出，以及目标目录和本地存储库中jar的jar -tvf：

    我使用maven-jar-plugin和像这样的maven-assembly-plugin的单一目标来使用它

    <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>3.1.0</version>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
            <configuration>
                <finalName>finalName</finalName>
                <archive>
                    <manifest>
                        <mainClass>
                            mainClass
                        </mainClass>
                    </manifest>
                </archive>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
            </configuration>
        </execution>
    </executions>
</plugin>

    无论如何，最重要的是告诉maven不使用maven-jar-plugin的这种配置生成默认jar

    <plugin>
    <artifactId>maven-jar-plugin</artifactId>
    <version>3.0.2</version>
    <executions>
        <execution>
            <id>default-jar</id>
            <phase>none</phase>
        </execution>
    </executions>
</plugin>

    你可以尝试设置为pom . 这将阻止创建 default jar .

    <project xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
                      http://maven.apache.org/xsd/maven-4.0.0.xsd">
  ...
  <packaging>pom</packaging>
  ...
</project>

    也许我错过了一些关于你的问题，但下面的代码让我成为一个可执行的jar：这是你在找什么？

    <plugin>
              <groupId>org.apache.maven.plugins</groupId>
              <artifactId>maven-jar-plugin</artifactId>
              <version>2.3.1</version>
              <configuration>
                    <archive>
                          <manifest>
                              <addClasspath>true</addClasspath>
                                <mainClass>some.main.class</mainClass>
                          </manifest>
                    </archive>
                    <finalName>Proj-${project.version}</finalName>
                    <outputDirectory>target</outputDirectory>
              </configuration>
        </plugin>

    您可以在下面使用此构建并使用以下命令进行编译：

    mvn clean compile assembly:single

    <build>
    <plugins>
        <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>3.1.0</version>
                <configuration>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                    <archive>
                        <manifest>
                            <mainClass>youMainClass</mainClass>
                        </manifest>
                    </archive>

                    <finalName>${artifactId}</finalName>
                    <appendAssemblyId>false</appendAssemblyId>
                </configuration>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
        </plugin>
