Running tests with jdk1.4

I want to run test for a legacy environment that uses jdk.1.4. If I do

test {

executable = “C:\Program Files (x86)\j2sdk1.4.2_01\bin\java.exe”; }

and “gradle test” then I get

Running tests with C:\Program Files (x86)\j2sdk1.4.2_01\bin\java.exe java.lang.UnsupportedClassVersionError: org/gradle/process/internal/launcher/GradleWorkerMain (Unsupported major.minor version 49.0)

at java.lang.ClassLoader.defineClass0(Native Method)

at java.net.URLClassLoader$1.run(URLClassLoader.java:194)

Is there a workaround for this?

Thanks

Well here’s one:

task jdk14test(type: Exec) {

commandLine “C:\Program Files (x86)\j2sdk1.4.2_01\bin\java.exe”, “-cp”, test.classpath.asPath, “junit.textui.TestRunner”, “com.xxx.yyyTest” }

If a test fails the exec return value lets gradle know that the build failed. Any better ideas?

Given that Gradle requires Java 1.5, this is going to be your best bet.

You may want to look at the dsl:org.gradle.api.tasks.JavaExec task.
