Error:java: 无效的标记: --add-exports=java.base/sun.net.util=ALL-UNNAMED

[liujiangang]

      Hi, I am using flink 1.9 in idea. But when I run a unit test in idea.
The idea reports the following error:"Error:java: 无效的标记:
--add-exports=java.base/sun.net.util=ALL-UNNAMED".
      Everything is ok when I use flink 1.6. I am using jdk 1.8. Is it
related to the java version?

[Till Rohrmann]

Try to reimport that maven project. This should resolve this issue.

Cheers,
Till

Hi
I met the same problem before. After some digging,  I find that the idea
will detect the JDK version
and choose whether to use the jdk11 option to run the flink maven building.
if you are in jdk11 env,  then
it will add the option --add-exports when maven building in IDEA.

For my case,  I was in IntelliJIdea2019.2 which depends on the jdk11, and
once I re-import the flink
modules then the IDEA will add the --add-exports flag even if  I removed
all the flags in .idea/compile.xml
explicitly.  I noticed that the Intellij's JDK affected the flink maven
building, so I turned to use the Intellij with JDK8
bundled,  then the problem was gone.

You can verify it, and if  it's really the same. can just replace your IDEA
with the pkg suffix with "with bundled JBR 8" in
here [1].
Say if you are using MacOS, then should download the package "2019.2.4 for
macOS with bundled JBR 8 (dmg)"

Hope it works for you
Thanks.

Hi,

I have encountered the same issue when setting up a dev environment.

It seems that the my Intellij (2019.2.1) unexpectedly activates java11
profile of maven. It doesn't match the Java compiler (JDK8). I'm not sure
why it happened silently.

So for me, the solution is "Intellij" -> "View" -> "Tool Windows" ->
"Maven" -> "Profiles" -> uncheck the "java11" -> reimport maven project.

Thanks,
Biao /'bɪ.aʊ/

I have the same problem when upgrade my IDEA to 2019.3.1.
And the Biao's solution works for me too.

Best,
Jark
