在maven测试阶段禁用Log4J日志 [英] Disabling Log4J logs during maven test phase

问题描述

在IDE中进行开发时，跟踪和调试日志会很有帮助，但在构建期间，我发现这些行非常令人不安，并且混淆了由maven或其他构建工具打印出来的报告。

Trace and debug logs can be helpful while doing development in the IDE, but during the build I find those lines quite disturbing, and obfuscating the report printed out by maven or other build tools.

让log4j尊重像 -Dlog4j.rootLogger = OFF ¹ 这样的系统属性与maven一起使用会很好不需要更改项目文件的东西。
我知道我可以指定 -Dlog4j.configuration = alternateconfig.props ² 但是我在这里要求找出是否有人发现了一种更智能的方法，可以在构建过程中禁即一些java类检测maven作为调用者，禁用log4j或其他智能解决方案。

It would be nice to have log4j honoring a system property like -Dlog4j.rootLogger=OFF¹ to use with maven or something which doesn't require changes on the project files. I know I can specify the -Dlog4j.configuration=alternateconfig.props ² but I'm asking here to find out if somebody found a smarter way to disable logging during the build process with minimal manual intervention. I.e. some java class detecting maven as caller that disables log4j, or other smart solutions.

任何提示？

备注：

[1]：已经尝试了，但它不起作用。

[1]: already tried, and it doesnt work.

[2]：这很不错，但它似乎不适用于maven（也许肯定会跳过它）

[2]: that's pretty good, but it doesn't seem to work well with maven (maybe surefire skips it)

推荐答案

正如<$ c $所解释的那样c> @artbristol （对问题的评论）这可以在surefire中配置。
可以在pom.xml中以这种方式完成：

As explained by @artbristol (comment on the question) this can be configured in surefire. It can be done in this way in the pom.xml:

        <plugin>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.5</version>
            <configuration>
                <forkMode>always</forkMode>
                <systemPropertyVariables>
                    <log4j.configuration>file:${basedir}/etc/log4j-silent.properties</log4j.configuration>
                </systemPropertyVariables>
            </configuration>
        </plugin>

然后，让文件 $ {basedir} / etc / log4j-silent .properties 使用以下设置可以解决问题：

Then, having the file ${basedir}/etc/log4j-silent.properties with following settings does the trick:

log4j.rootLogger=OFF

在maven的测试运行期间，log4j被完全禁用，并且一切都在IDE中正常工作。

The log4j gets completely disabled during test runs in maven, and everything works normally in the IDE.

更好的解决方案是不要有额外的配置文件;但到目前为止找不到它。

A better solution would be not to have the additional configuration file; but can't find it so far.
