Question

我认为我已经设置了与Maven一起运行jenkins工作所需的外包，但每次我的工作时我都会遇到错误。我使用的是Ubuntu 14.04 LTS和Jenkins 1.642。

完整错误：

Java Home环境变量和版本检查：

damian@damian-server:~$ echo $JAVA_HOME
/usr/lib/jvm/java-8-oracle
damian@damian-server:~$ java -version
java version "1.8.0_77"
Java(TM) SE Runtime Environment (build 1.8.0_77-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)

Maven Home环境变量和版本检查：

damian@damian-server:~$ echo $M2_HOME
/home/damian/Documents/apache-maven-3.3.9
damian@damian-server:~$ mvn -version
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T13:41:47-03:00)
Maven home: /home/damian/Documents/apache-maven-3.3.9

Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.13.0-35-generic", arch: "amd64", family: "unix"

Jenkins config，MAVEN_HOME：/home/damian/Documents/apache-maven-3.3.9 /

如果我在终端中运行Maven工作得很好。

有什么想法吗？

感谢。

在pom.xml中配置Maven-jar-plugin，以在构建阶段设置项目的主类。

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <archive>
                    <manifest>
                        <mainClass>your.main.Class</mainClass>
                    </manifest>
                </archive>
            </configuration>
        </plugin>

    </plugins>
</build>

启动jenkins作业时无法找到或加载主类mvn
