使用sofaboot 3.0 和 jarslink2.0 进行项目动态部署时报异常， 属于启动异常

[iteaj]

Describe the bug

使用jarslink动态管理多个应用， 采用的是合并部署里面动态打包部署， 要求是能在多个应用之间进行jvm服务通信

以下是报出的异常： java.lang.LinkageError: loader constraint violation: loader (instance of com/alipay/sofa/ark/container/service/classloader/PluginClassLoader) previously initiated loading for a different type with name "org/slf4j/Logger" at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$100(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at com.alipay.sofa.ark.container.service.classloader.AbstractClasspathClassloader.resolveLocalClass(AbstractClasspathClassloader.java:245) at com.alipay.sofa.ark.container.service.classloader.PluginClassLoader.loadClassInternal(PluginClassLoader.java:79) at com.alipay.sofa.ark.container.service.classloader.AbstractClasspathClassloader.loadClass(AbstractClasspathClassloader.java:66) at java.lang.ClassLoader.loadClass(Unknown Source) at org.slf4j.LoggerFactory.(LoggerFactory.java:86) at com.alipay.sofa.common.log.Constants.(Constants.java:31) at com.alipay.sofa.common.utils.ReportUtil.reportWarn(ReportUtil.java:37) at com.alipay.sofa.common.log.MultiAppLoggerSpaceManager.createILoggerFactory(MultiAppLoggerSpaceManager.java:274) at com.alipay.sofa.common.log.MultiAppLoggerSpaceManager.getILoggerFactoryBySpaceName(MultiAppLoggerSpaceManager.java:220) at com.alipay.sofa.common.log.MultiAppLoggerSpaceManager.getLoggerBySpace(MultiAppLoggerSpaceManager.java:171) at com.alipay.sofa.common.log.MultiAppLoggerSpaceManager.getLoggerBySpace(MultiAppLoggerSpaceManager.java:115) at com.alipay.sofa.common.log.LoggerSpaceManager.getLoggerBySpace(LoggerSpaceManager.java:57) at com.alipay.sofa.common.log.LoggerSpaceManager.getLoggerBySpace(LoggerSpaceManager.java:42) at com.alipay.sofa.runtime.spi.log.SofaRuntimeLoggerFactory.getLogger(SofaRuntimeLoggerFactory.java:41) at com.alipay.sofa.runtime.spi.log.SofaRuntimeLoggerFactory.getLogger(SofaRuntimeLoggerFactory.java:53) at com.alipay.sofa.runtime.spring.initializer.SofaRuntimeSpringContextInitializer.initialize(SofaRuntimeSpringContextInitializer.java:44) at org.springframework.boot.SpringApplication.applyInitializers(SpringApplication.java:633) at org.springframework.boot.SpringApplication.prepareContext(SpringApplication.java:373) at org.springframework.boot.SpringApplication.run(SpringApplication.java:325) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1255) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1243) at com.iteaj.ark.ArkApplication.main(ArkApplication.java:14)

Expected behavior

        <groupId>com.alipay.sofa</groupId>
        <artifactId>runtime-sofa-boot-plugin</artifactId>
    </dependency>

@iteaj 感谢反馈，确认是我们代码问题。已经修复，麻烦将本地 runtime-sofa-boot-plugin 3.0.0-SNAPSHOT 包删除，拉取最新的修复包

[iteaj]

我刚才拉取试了以下， 启动还是报错， 这个问题是什么原因导致的， 找了很久，都没找出问题的原因  题

[QilongZhang]

@iteaj 你清空了本地缓存吗？ 修复之后的包应该是不会报错的。

修复 PR 在 https://github.com/alipay/sofa-boot/pull/259 .

好的， 刚才重新拉了以下，已经可以
