1、jar包封装完成后,其他项目引用jar,启动时报错java.lang.SecurityException: Invalid signature file digest for Manifest main attributes
这是因为jar中MATE-INF目录下存在*.SF,*.DSA,*.RSA文件,这些文件中有签名导致错误,删除即可
推荐直接在打包的时候排除掉 pom如下:
<build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <version>3.3.0</version> <configuration> <!-- put your configurations here --> <filters> <filter> <artifact>*:*</artifact> <excludes> <exclude>META-INF/*.SF</exclude> <exclude>META-INF/*.DSA</exclude> <exclude>META-INF/*.RSA</exclude> </excludes> </filter> </filters> </configuration> <executions> <execution> <phase>package</phase> <goals> <goal>shade</goal> </goals> </execution> </executions> </plugin> </plugins> </build>
2、maven依赖冲突
idea使用maven helper插件查看依赖冲突,https://plugins.jetbrains.com/plugin/7179-maven-helper
