如何在Jenkins中将环境变量传递到sbt测试构建步骤? [英] How to pass environment variables to a sbt test build step in Jenkins?

问题描述

在我的scala测试中，我通过sys.props.getOrElse("cassandra.test.host", DEFAULT_CASSANDRA_TEST_HOST)读取了一个环境变量.

In my scala test, I read an environemnt variable via sys.props.getOrElse("cassandra.test.host", DEFAULT_CASSANDRA_TEST_HOST).

测试通过Jenkins运行.

The tests are run via Jenkins.

我已经添加了Build using sbt作为构建步骤.

I have added a Build using sbt as a build step.

通过在SO上研究类似的问题，我想出了这个解决方案-即将操作"字段设置为:

By looking at similar questions on SO, I came up with this solution - i.e. setting the Actions field to:

'; set javaOptions += "-Dcassandra.test.host=XX.XXX.XXX.XXX"; test'

但是它不起作用.执行Properties.envOrElse时未设置任何变量.

But it doesnt work. No variable is set when Properties.envOrElse is executed.

Jenkins控制台输出包含:

The Jenkins console output contains:

[...] [util-sessionizer] $ java -jar /usr/local/bin/sbt-launch.jar '; set javaOptions += "-Dcassandra.test.host=XX.XXX.XXX.XXX"; test' [info] Loading project definition from /jenkins/workspace/util-sessionizer/project/project [info] Loading project definition from /jenkins/workspace/util-sessionizer/project [info] Set current project to util-sessionizer (in build file:/jenkins/workspace/util-sessionizer/) [info] Defining *:javaOptions [info] The new value will be used by *:runner, compile:run::runner and 4 others.

推荐答案

如果您不使用新的JVM执行测试，则设置javaOptions不会执行任何操作. 摘自SBT:

If you're not forking a new JVM to execute your tests, setting javaOptions does nothing. Excerpt from SBT itself:

> help javaOptions
Options passed to a new JVM when forking.

这说明了在不进行测试分叉时为什么不使用javaOptions的原因.

This explains why your javaOptions are not used when you're not forking your tests.

您基本上有两种解决方案:

You have basically two solutions:

• 要么设置fork in Test := true以便在派生的JVM中运行测试

• 或将系统属性传递给SBT本身:

• Either set fork in Test := true to run your tests in forked JVMs

• Or pass your system properties to SBT itself :

sbt -Dcassandra.test.host=XX.XXX.XXX.XXX test
