Unable to run keycloak performance testsuite

I followed the steps provided by this README.md file
Keycloak testsuite readme

I am able to build the project but however when I run
cd testsuite/performance
mvn clean install

I am getting

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.8:run (configure-infinispan) on project performance-keycloak-infinispan-server: An Ant BuildException has occured: The following error occurred while executing this line:

Has anyone come across this issue and resolved it.
I tried there issue tracker but it hosted separately and not previous such stacktrace is there.

TLDR; If you need to take a performance test on Keycloak try the newer version https://github.com/keycloak/keycloak-benchmark instead.

I met the same issue on Keycloak 12.0.4, below is my research:

I found ispn-cli.sh is the old name of infinispan cli. Now the name is cli.sh
But event if you rename the cli.sh to ispn-cli.sh, it won't work. Because you will meet another issue like below, which means missing ...standalone/configuration/clustered.xml for short.

main:

check-configuration-state:
     [echo] configured: ${configured}
     [echo] management.configured: ${management.configured}

configure-infinispan:

So I went through Keycloak git history and found this commit https://github.com/keycloak/keycloak/commit/df68ca8dcfd481ee64801fbc2cecaa0a6359285d
The infinispan version was based on jboss/infinispan-server:8.2.6.Final. Then, I checked the most closest version of infinispan-server(because 8.2.6.Final is not found anymore), it has all the necessary files.

$ unzip -l infinispan-server-8.1.3.Final-bin.zip | grep -E "standalone/configuration/|ispn-cli.sh"
        0  2016-04-04 08:51   infinispan-server-8.1.3.Final/standalone/configuration/
     2500  2016-04-04 08:51   infinispan-server-8.1.3.Final/bin/ispn-cli.sh
    17968  2016-04-04 08:51   infinispan-server-8.1.3.Final/standalone/configuration/clustered.xml
     1112  2016-04-04 08:51   infinispan-server-8.1.3.Final/standalone/configuration/mgmt-users.properties
      711  2016-04-04 08:51   infinispan-server-8.1.3.Final/standalone/configuration/application-roles.properties
     2697  2016-04-04 08:51   infinispan-server-8.1.3.Final/standalone/configuration/logging.properties
      669  2016-04-04 08:51   infinispan-server-8.1.3.Final/standalone/configuration/mgmt-groups.properties
    12084  2016-04-04 08:51   infinispan-server-8.1.3.Final/standalone/configuration/standalone.xml
      935  2016-04-04 08:51   infinispan-server-8.1.3.Final/standalone/configuration/application-users.properties

Besides that, I found this, which is saying infinispan.version is based on root config. That means infinispan has changed a lot, but testsuite/performance/infinispan isn't keep up to date.

// testsuite/performance/infinispan/pom.xml
        <infinispan.artifactId>infinispan-server-build</infinispan.artifactId>
        <!--infinispan.version is located in the root pom.xml--> 
        <infinispan.unpacked.folder.name>infinispan-server-${infinispan.version}</infinispan.unpacked.folder.name>

And infinispan module was removed in this commit:
https://github.com/keycloak/keycloak/commit/54c5b1514f0611056f38053081d094cf5e5fd08a#diff-bc3567ad76edc320e3fa85c5e0e5380e09c11f94c8395b80064e195f2ef82793

So, I strongly doubt Keycloak testsuite/performance is stalled.
