Error when running JUnit: Fixing in build.xml

I am inheriting a project. I have recently updated Proguard and JUnit versions and am having a problem running the command ant jtest.

Versions of software I currently have:

Java 1.8.0_141

Ant 1.10.1

Proguard: recently updated to 5.3.3, was 4.9

JUnit: recently updated to 4.12, was 4.10

The test suite runs fine in Eclipse, but when running from Cygwin with the command I get this error at the end of the output:

jtest:

Here is my build.xml file

I am not very familiar with build.xml files. I understand that this error is because JUnit has a dependency of hamcrest-core-1.3.jar. How can I point JUnit at the hamcrest-core-1.3.jar file in order to make this command work? Can I do it from build.xml?

Solution

  • Your jtest target runs junit with this classpath:

    <path id="test.classpath">
    <pathelement location="${testclassesdir}" />
    <pathelement location="${builddir}/project.jar" />
    <path refid="project.libs" />
    <pathelement location="${toolsdir}/junit4.12/junit-4.12.jar" />
</path>

    You need to add hamcrest-core-1.3.jar to that classpath. You can do this by creating a directory name "hamcrest1.3" to your ${toolsdir} and downloading hamcrest-core-1.3.jar into that directory and then updating the test.classpath to add this pathelement:

    <pathelement location="${toolsdir}/hamcrest1.3/hamcrest-core-1.3.jar" />
