JUnit 5 Console does not find tests - unit-testing

Question

I am using JUnit5 Console in my Ant build script. However it does not find any tests in my project.
I've used the following command in Terminal:
-jar lib\junit-platform-console-standalone-1.1.0-RC1.jar --class-path bin --scan-class-path
which returns:
[36m.[0m
[36m+--[0m [36mJUnit Jupiter[0m [32m[OK][0m
[36m'--[0m [36mJUnit Vintage[0m [32m[OK][0m
Test run finished after 27 ms
[ 2 containers found ]
[ 0 containers skipped ]
[ 2 containers started ]
[ 0 containers aborted ]
[ 2 containers successful ]
[ 0 containers failed ]
[ 0 tests found ]
[ 0 tests skipped ]
[ 0 tests started ]
[ 0 tests aborted ]
[ 0 tests successful ]
[ 0 tests failed ]
I get the same output for the Ant script:
<target name="test" depends="compile" description="Runs JUnit Tests">
<java jar="lib\junit-platform-console-standalone-1.1.0-RC1.jar" fork="true">
<arg value="d ."/>
<arg value="-details verbose"/>
</java>
</target>

Answer 1

I fixed it: The Arguments have to be lines:
<target name="test" depends="test-javac" description="Runs JUnit Tests">
<java jar="${junit.jar}" fork="true">
<arg line="--class-path bin"/>
<arg line="--scan-class-path"/>
<arg line="--reports-dir reports"/>
<!-- Available options: [ascii,unicode]-->
<arg line="details-theme unicode"/>
<!-- Available options: [none,flat,tree,verbose]-->
<arg line="--details tree"/>
</java>
</target>

You need to specify where the launcher can find your compiled test classes. See https://junit.org/junit5/docs/current/user-guide/#running-tests-console-launcher for details.
How are your test classes named? Are they stored by "javac" directly under "bin/"?
Maybe the answer and comments posted here Unable to run tests with JUnit5 Console Launcher are helpful.
