jar在Linux运行报错问题解决

终极解决方法:java -cp xxxxx.jar 包.main函数所在类;

例子:java -cp java_linux_dep_t-1.4-SNAPSHOT.jar com.test.run.MainEntry

执行指令   java -jar  xxxxx.jar

错误1:no main manifest attribute, in xxxxxxx.jar

原因:找不到main方法

解决:在pom.xml中添加如下插件配置(其中mainClass项需要根据自己的类名进行修改;只需要写类名,不需要加groupId和artifactId !!!

<build>
        <plugins>
            <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">
                                    <mainClass>这里只写main函数所在类名即可</mainClass>
                                </transformer>
                            </transformers>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

错误2:Error: Could not find or load main class com.ab.java_linux_dep_t.main_entry

原因:上面说的mainClass配置错误

解决:mainClass中只需要写类名,不需要加groupId和artifactId !!!
