I am getting '**** WRONG JAVA VERSION ****' on running ant build

Question

My question is not this question, because I have no discrepancy in java versions. The build on running 'ant clean all' is failing after I installed java 1.8.45 (both jdk and jre). It says:

**** WRONG JAVA VERSION ****

Environment check failed: You are using a not supported version of Java. Please make sure you are using Java version 1.7 or later. Your current Java version is: 1.8.0_45

TIP: If you are using eclipse you can configure a different JVM under Preferences->Java->Installed JREs.

Details of my system:
Java version:

java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

Javac Version:

javac 1.8.0_45

Clean tag of build.xml:

<target name="clean" description="Cleans platform and all extensions">
        <callback extname="" target="before_clean"/>
        <clean/>
        <callback extname="" target="after_clean"/>
    </target>

Unlike other open threads for the same issue, in this case all the versions are coherent and ant is acknowledging it. Still, it is giving this issue. Any insight?

Higa

See this - #950178 – Puddle

what is the JAVA_HOME environment variable? – Adrieneadrienne

@harish.raj: I have already tried the solution mentioned there.The problem is that I am not getting any discrepancy on checking the various versions, still I am facing this issue. – Higa

@krock: java_home is set to 'C:\Program Files\Java\jdk1.8.0_45' – Higa

I suspect it might be an issue with the defined "clean" target in the build.xml, can you add the clean target definition to your description? – Doublethink

@CeilingGecko: Can you please suggest how to do that? – Higa

You are running ant commands from somewhere right? either it's an ant script or configured IDE or whatever, somewhere there should be a defined location where a build.xml is located, once you locate that find the xml element which starts with <target name="clean"> (or something like that), select that until the </target> closing tag and paste it in the description. – Doublethink

@CeilingGecko: Added clean tag in the question. – Higa

it looks like it's making calls to the before_clean and after_clean targets could you add those in as well? Also check if there is a <taskdef name="clean"> defined there anywhere as well, if you find it, please add that as well. – Doublethink

@CeilingGecko: There is not separate tag for before_clean, after_clean or <taskdef name="clean"> Could this be a problem of ant compatibility as java 1.8.45 is the latest java release. How do I check ant compatibility? – Higa

@QualtarDemix are there any import tags defined? Those targets/taskdefs might be defined in other xml files and then imported. – Doublethink

@CeilingGecko: You are right. There are various import tags pointing to other files. However, all these files, in fact my entire platform folder and my entire project does not have a definition for these tags. They are referring to these tags as target but before_clean or after_clean are not defined anywhere. – Higa

Your output is not generated by Ant itself, it must be something inside your build file. Ant 1.9.x itself requires Java 1.5, it is a long way away from requiring 1.7. – Katharinekatharsis

Answer 1

Got it!!!
java 1.8.45 is not compatible with ant 1.9.1. Switched to java 1.7.67 (both jdk and jre) and everything is working fine.

Higa

Why don't you change to a newer version of Ant? The latest is 1.9.4. – Aldric

Answer 2

We can configure the java version util.xml Location: ${HYBRIS_BIN_DIR}\platform\resources\ant\util.xml .

Consider my version is 1.8, under checkenv configure the java version as contains string="${java.version}" substring="1.8" />

            <if>
            <not>
                <or>
                    <contains string="${java.version}" substring="1.7" />
                    <contains string="${java.version}" substring="1.8" />
                </or>
            </not>
            <then>
