在示例项目上打开Liberty日志配置异常
在示例项目上打开Liberty日志配置异常
提问于 2018-10-25 11:00:20
我正尝试在Fedora28上运行OpenLiberty java服务器，但无法从OpenLiberty主页启动示例应用程序。
说明书上写着：
git clone https://github.com/OpenLiberty/sample-getting-started.git
cd sample-getting-started
mvn clean package liberty:run-server当我运行服务器时，我得到了一个构建失败，错误如下：
Caused by: org.apache.commons.logging.LogConfigurationException:
User-specified log class 'org.codehaus.mojo.pluginsupport.logging.DelegatingLog' cannot be found or is not useable.我尝试清除maven缓存并执行另一个mvn install，但仍然没有帮助。这个项目在我的macbook上运行得很好。有什么办法解决这个问题吗？
其他日志：
这是我在运行mvn clean package liberty:run-server后得到的内容的简化版本

我也遇到过这个问题。
最后，事实证明是opensuse提供的maven版本造成的，或者是我选择的随附安装的插件。
在切换到官方的Maven二进制文件之后，这个问题就消失了。

对于OpenSUSE，请按照Filip Paczyński所说的做。切换到maven的官方版本。
OS maven发行版(当前为3.6.3)中缺少某些内容。有了官方版本，一切都运行得很好。我安装了3.8.1的最新版本，但可能旧版本也可以。只需跳过操作系统。
附言:遗憾的是，我还没有对菲利普的回答发表评论。所以..。很抱歉放大了页面。

尝试将插件依赖项添加到旅行车-http：
<dependencies>
<dependency>
<groupId>org.apache.maven.wagon</groupId>
<artifactId>wagon-http</artifactId>
<version>3.2.0</version>
</dependency>
</dependencies>我在一个多模块项目中遇到了和你一样的错误，似乎错误User-specified log class 'org.codehaus.mojo.pluginsupport.logging.DelegatingLog' cannot be found or is not useable不是问题本身的原因，而是插件试图记录问题时的第二个错误。
直接在模块中运行插件，我会得到这个错误：[WARNING] Error injecting: org.apache.maven.wagon.providers.http.HttpWagon java.lang.ExceptionInInitializerError
您的堆栈跟踪中有一个类似的错误，因此将依赖项添加到http http中为我修复了它。
下面是我的maven + Java配置：
