Unable to build on Windows

[xmenxwk]

I've tryiing to build its sample app for 2 hours but everywhere errors and errors. Its not straight forward as written in description. Would you you please fix it ?

Im using android studio and trying to checkout using https url. Before I tried with github terminal, but no success.

[TWiStErRob]

Did you do the submodule part? Try to make it work in terminal first and then import to AS.

[xmenxwk]

Could you please write in steps ?

Im using Windows 7

[xmenxwk]

This is the error Im getting when I use "gradlew jar" in cmd

I managed to build on Windows 7 when I did it using
https://github.com/bumptech/glide/blob/master/README.md#build
and I think I used JDK 6, and latest Android SDK.

[TWiStErRob]

Ahh that thing, I fixed that, but it didn't make it to master. Let me dig it up.

[TWiStErRob]

library/build.gradle from #272

[TWiStErRob]

As an alternative you can temporarily skip a task, but that doesn't help if you want to import it into AS.

[xmenxwk]

it started downloading more files then this

is java 1.8 not supported ?

[xmenxwk]

Nevermind, I changed the JAVA_HOME and JDK_HOME to java 1.7 and its now keep going.

[TWiStErRob]

Android supports Java 7 since 4.4, but Glide builds with Java 6 to be compatible with most Android builds. Use JDK 6. FindBugs must have their own reasons why it is not forward compatible.

now new error

I'd recommend considering VirtualBox + Linux. Since travis-ci only supports Linux, Linux is the only officially supported platform. I develop regularly on OSX, so that's likely to work.

I don't object to supporting Windows, but until we have some CI setup for it it's likely to continue to btrsk. I wouldn't object to a pull request adding ci support for windows. AppVeyor might be a possibility.

[TWiStErRob]

Rename DiskLruCacheTest.java to have a different extension.
disklrucache was written for Android/unix and the Windows file system has different quirks so it won't run because the tests assume unix-like file system behaviour, see JakeWharton/DiskLruCache#70 (comment)

[xmenxwk]

@sjudd : Yes I will be using linux soon, but right now I need this on Windows.

@TWiStErRob : renamed, same error. Is there any parameter to skip the tests ?

[TWiStErRob]

Try a clean build, the .class file probably stuck. Thinking twice it's best to remove the test file, not just rename.
To skip: as referenced above something like: -x :third_party:disklrucache:testBlah would help. Check the last task name above the failure.

[xmenxwk]

Thank you very much, @TWiStErRob :)

[sjudd]

Since we haven't checked anything in to fix this and someone else may find it useful, let's leave this open for now.

[TWiStErRob]

There's a failure in library/build.gradle where files can't handle multiple jars in asPath. Since FindBugs.classpath is a FileCollection and Configuration extends FileCollection the following works: replace
classpath = files(project.configurations.compile.asPath)
with
classpath = project.configurations.compile

[TWiStErRob]

DiskLruCacheTest fails at least 8 test methods, so I think it's easier to disable all:

@BeforeClass public static void setUpClass() {
    Assume.assumeThat(System.getProperty("os.name"),
            IsNot.not(StringStartsWith.startsWith("Windows")));
}

This would still allow Travis to catch bugs, but also allow people on Windows to build.

[TWiStErRob]

@sjudd this can be closed now, thank you for putting the fixes in.
It builds flawlessly without any hacks. The key is to use the correct java version.

(DiskLruCache commit for reference: sjudd/DiskLruCache@cd49c1d)

[sjudd]

Great, glad to hear it.

[TWiStErRob]

Dang, I missed one, I had it in local changes:
disklrucache/checkstyle.xml:

    <module name="NewlineAtEndOfFile">
        <property name="lineSeparator" value="lf" />
    </module>

[sjudd]

Should be fixed here: ae4a451
