正如您在最后一行中看到的，要编译项目，需要启动“主”应用程序。 当主应用程序启动时，logback 也启动。
我们有一个配置文件，其中有环境变量，如下（以loki Appender为例，但这个问题一般是针对logback的）
<appender name="LOKI" class="com.github.loki4j.logback.Loki4jAppender">
<metricsEnabled>true</metricsEnabled>
<http>
<url>${LOGS_HOST}</url>
<auth>
<username>${LOGS_USER}</username>
<password>${LOGS_TOKEN}</password>
</auth>
</http>
<format>
<label>
对于本地机器，测试环境，生产环境，这些环境变量总是被设置的。
但是，当我们只需要构建应用程序时（不运行它，这里不需要日志）。 由于变量不存在，这将无法开始。

我尝试在编译时禁用 logback。但没有运气。
删除对 logback 的依赖可以解决编译时的问题，但在运行时，我们会完全丢失日志，这是不可能的。
如何在编译时禁用logback？
最简单的方法是下面的条件 logback 附加程序，您可以看到 logback.xml
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<if condition='isDefined("lokiHost")'>
<then>
<appender name="LOKI" class="com.github.loki4j.logback.Loki4jAppender">
<http>
<url>http://${lokiHost}:3100/loki/api/v1/push</url>
</http>
<format>
<label>
<pattern>app=my-app,host=${HOSTNAME}</pattern>
</label>
<message>
<pattern>%-5level [%.5(${HOSTNAME})] %.10thread %logger{20} | %msg %ex</pattern>
</message>
</format>
</appender>
<root level="INFO">
<appender-ref ref="LOKI"/>
<appender-ref ref="CONSOLE"/>
</root>
</then>
<else>
<root level="INFO">
<appender-ref ref="CONSOLE"/>
</root>
</else>
</if>
</configuration>
在所需的依赖项之下，logback 条件附加程序配置需要 janino
<dependency>
<groupId>org.codehaus.janino</groupId>
<artifactId>janino</artifactId>
<version>3.1.12</version>
</dependency>
<dependency>
<groupId>com.github.loki4j</groupId>
