An unexpected error occurred while launching the test runtime

Question

I'm launching the test suite of an eclipse plugin project with org.eclipse.tycho:tycho-surefire-plugin:4.0.7:test.

The process crashes before being able to run any test.

Error on Windows:

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-surefire-plugin:4.0.7:test (default-test) on project org.scala-ide.sdt.core.tests: An unexpected error occurred while launching the test runtime (process returned error code 1 (HRESULT Code 0x1, check for example https://www.hresult.info/ for further details)).

Same error on linux:

I reduced the pom to a smaller one to remove the sections that have nothing to do with test execution:

After a google search, I found this issue linked by this one on Github and tried to add <useJDK>BREE</useJDK>, which didn't help.

Also, it appeared that I might need a toolchain configuration, so I created this ~/.m2/toolchains.xml:

<toolchains>
   <toolchain>
      <type>jdk</type>
      <provides>
         <id>JavaSE-17</id>
         <version>17</version>
      </provides>
      <configuration>
         <jdkHome>C:\Users\nicol\Downloads\jdk-17.0.4_windows-x64_bin\jdk-17.0.4</jdkHome>
      </configuration>
   </toolchain>
</toolchains>

But I'm still having the issue. What did I miss ?

Answer 1

The reason is an unsupported jvm argument :

-XX:+UnsyncloadClass

The errors are not output to the console even in debug mode (-e -X). The java command has to be run separately to see the error:

Unrecognized VM option 'UnsyncloadClass'
