Simon commented on SUREFIRE-1923:
---------------------------------
{quote} I consider this a a non-issue/misunderstanding.
{quote}
I run maven with java 11 (or higher) but with a toolchain targeting JDK7 with
something which looks like :
{code:xml}
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<jdkToolchain>
<version>1.7</version>
</jdkToolchain>
</configuration>
</plugin>
{code}
And that failed with error reported above.
I can understand that you don't consider this as a surefire bug but from a user
point of view this is an issue to not be able to do that.
I know this is probably obvious for you but from a user point of view this not
clear that the minimal usable toolchain version is the same as the minimal
java version required for surefire plugin. (Maybe some documentation is needed
here)
*Why this is a real use case ?*
You create/maintain a java library.
You want to use recent maven tooling, so you need to be able to launch it with
recent version of java.
But you want to compile it to old version of java to make your library
compatible with most use case as possible, so you are using `--release` option.
All is good except you want to be sure the code works well on this old version
of JDK, so you want to execute your tests with it.
Great, surefire allow that with *toolchain* but you can not use less than JDK8
... 😢
I understand that whole surefire plugin will not be stuck to very very old
version of java but maybe this is possible to isolate the code which is needed
to run tests with toolchain and make it compatible with very very old version
of java. (I don't know surefire code, so maybe this last sentence doesn't make
sense at all 😅...)
