ear文件部署在Wildfly上，无法破解原因。有什么线索吗？

尝试重新安装...重新打包、maven 更新/刷新，但没有成功。

Answer 1

这里:

<dependency>
  <groupId>com.koinplus</groupId>  
   <artifactId>KoinPlusCommons</artifactId>  
   <version>1.0</version> 
   <scope>system</scope>
   <systemPath>C://Users/trbrewjars/KoinPlusCommons-1.0.jar</systemPath>
 </dependency>

<dependency>
  <groupId>com.trbrew.common</groupId>  
   <artifactId>TrBrewCommons</artifactId>  
   <version>1.0</version> 
   <scope>system</scope>
   <systemPath>C://Users/trbrewjars/TrendBrewCommons-1.0.jar</systemPath>
 </dependency>

您使用系统范围声明您的依赖项。
它可以防止您在 TrBrewCommerce Artifact 的解析中以及最终的 EAR Artifact 中拥有这些依赖项。
如果您希望将这些 jar 包含在您的 EAR 中，那么使用技巧来保留 system 范围并不是一个干净的构建。
更简洁的方法是将这两个 jar 安装到您的 Maven 存储库中。之后，您可以删除依赖项声明中的范围system(在本例中，默认情况下将使用范围runtime)和系统路径，例如:

<dependency>
  <groupId>com.koinplus</groupId>  
   <artifactId>KoinPlusCommons</artifactId>  
   <version>1.0</version> 
 </dependency>

<dependency>
  <groupId>com.trbrew.common</groupId>  
   <artifactId>TrBrewCommons</artifactId>  
   <version>1.0</version> 
 </dependency>

要安装 Maven Artifact ，您有 install-file 目标:
