However I only want to compile one of those files initially so that I can then use it to update the other classes in the package.

It's a factory for the other classes and as a result is dependent on them - ie. I've been attempting to use a JavaCompile gradle task to do this. As a result I've read the documentation for JavaCompile and attempted to search for examples but seems there is very little out there. I've even posted on the gradle forumsbut slow going so far.

Gradle Compile-only Dependencies

I'm able to do what is required readily with an ant script using the ant javac task. But I'd like to do it in gradle and without using the ant. Both files are in a package called some. It's as though the sourcedir is not pointing where it should - and indeed as though I was just running javac on the command line.

I was thinking the gradle 'JavaCompile' task's 'source' property was working like the ant 'srcdir' property, but that appears to not be the case.

So here is the gradle script I'm currently trying:. Thanks to the discussion with PeterNiederwieser on the original post in the comments, I'll provide the answer here for completeness. To have gradle JavaCompile function in a manner very similar to the ant javac, you need to provide the sourcepath compiler option via the options. Therefore, the gradle script that now works is as follows:. Note specifically the last line the only difference which allows all to work. The result of which is that it will actually compile both ClassOne and ClassTwo at build time - rather than only attempting the single explicit file you specified.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

What about compileOnly? My use case is a multi-module sorry I don't like Gradle's multi-project terminology project, where I have an Android app, and multiple libraries that the app depends on implementation. Some of the libraries also depend on one another. Should I use implementation or compileOnly when declaring dependencies in the library modules?

My app module will be using implementation to depend on those artifacts, so I don't need them to be transitive through the library modules. The api configuration should be used for dependencies that are exported to external modules transitive dependency. Vice-Versa implementation configuration should be used for dependencies that are internal to the component not transitive dependency. So compileOnly doesn't replace the implementation configuration job e.

Since your case is a "multi-module", you have to use the api configuration, until you reach the final module it's better to use implementation.

I think api requires more memory because gradle will snapshot every class in that transitive modulevice versa implementation is a preferred configuration because as mentioned above it's used for its own internal implementations.

If you module does not need those dependencies on runtime I see no issues declaring them compileOnly.

Still not quite there. The gradle doc for compileOnly says "Dependencies whose API is required at compile time but whose implementation is to be provided by a consuming library, application or runtime environment.

Eliezer as azizbekian suggest in comments, if you don't need module in run-time yes use compileOnly this well reduce memory usage. Eliezer sry, i didn't under stand that, what you mean? Is using compileOnly going to give better performance than using implementation sure. Sign up or log in Sign up using Google. Sign up using Facebook.

I am basically looking for a way to mimic the maven dependency provided. I am building a jar an extension to a db driverwhich depends on another jar the db driverbut I do not want to include that jar. I am able to use compileOnly to achieve that, however now the tests won't run or compile as the required jar is not included in tests.

I tried through the list of available dependencies like testCompilehowever I could not find one that makes the jar available at compile time and when the tests run and compile. You can extend your testCompile configuration from the compileOnly configuration:. Learn more. Gradle dependency for compile time only and test Ask Question.

The three configurations all add a dependency to the compile phase of the build, when your java code is being compiled into bytecode. So compile is the one that is easiest to understand. You are declaring a dependency that your java code needs to compile cleanly.

Configurations

As a best practice, you only want to list compile dependencies on those libraries that you really need to compile your code. As transitive dependencies, Gradle will handle those for you. When the compile occurs, this dependency will be included in the classpath for javac to compile your java source file. Additionally, when it comes time to build the jar, packages that you use in your java code from POI will be added as Import-Package manifest entries.

It is this addition which will result in the "Unresolved Reference" error about the missing package if it is not available from some other module in the OSGi container. For those with a Maven background, the compile configuration is the same as Maven's compile scope. The compileOnly configuration is used to itemize a dependency that you need to compile your code, same as compile above.

The difference is that packages your java code use from a compileOnly dependency will not be listed as Import-Package manifest entries. The common example for using compileOnly typically resolves around use of annotations. I like to use FindBugs on my code don't laugh, it has saved my bacon a few times and I feel I deliver better code when I follow its suggestions. Sometimes, however, FindBugs gets a false positive result, something it thinks is a bug but I know it is exactly how I need it to be.

So the normal solution here is to add the SuppressFBWarninsg annotation on the method; here's one I used recently:. FindBugs was complaining that I didn't check key for null, but it is actually emitting within the processing of a Map entry, so the key can never be null. Rather than add the null check, I added the annotation.

I used compileOnly in this case because I only need the annotation for the compile itself; the compile will strip out the annotation info from the bytecode because it is not a runtime annotation, so I do not need this dependency after the compile is done.

In OSGi, we will also tend to use compileOnly for the org. The compileInclude configuration was actually introduced by Liferay and is included in Liferay's Gradle plugins.

The compileInclude configuration replaces the manual steps from my OSGi Depencencies blog post, option 4including the jars in the bundle. In fact, everything my blog talks about with adding the Bundle-ClassPath directive and the -includeresource instruction to the bnd. Where compileInclude shines, though, is that it will also include some of the transitive dependencies into the module as well.

Note how I said that some of the transitive dependencies are included? I've had cases where it missed a particular transitive dependency. I do know it will not include optional dependencies and that may have been the cause in those cases. To fix it though, I would just add a compileInclude configuration line for the missing transitive dependency. You can disable the transitive dependency inclusion by adding a flag at the end of the declaration.

For example, if I only wanted poi-ooxml but for some reason didn't want it's transitive dependencies, I could use the following:. It's then up to you to include or exclude the transitive dependencies, but at least you won't need to manually update the bnd. If you're getting the impression that compileInclude will mostly work but may make some bad choices including some you don't want and excluding some that you needyou would be correct.

It will never offer you the type of precise control you can have by using Bundle-ClassPath and -includeresource. It just happens to be a lot less work. For those who use Maven, I'm sorry but you're kind of out of luck as there is no corresponding Maven scope for this one. If you need recommendations of what configuration to use when, I guess I would offer the following:.

When I run. Strangely, IntelliJ resolves compileOnly dependencies properly, but not annotationProcessor. In Gradle, a platform, like regular dependencies, is scoped to a given configuration and the configurations extending it. In your example, the BOM is only used in implementation and thus will only provide recommendations for that configuration and the ones extending it, like compileClasspath or runtimeClasspath.

In order to solve your issue, you will need to declare the BOM to all the configurations where you want to benefit from its recommended versions. Learn more. Asked 1 year, 2 months ago.

They are not included on the runtime classpath and are non-transitive, meaning they are not included in dependent projects. This is true when using Gradle project dependencies and also when publishing to Maven or Ivy repositories. In the latter case, compile only dependencies are simply omitted from published metadata.

With Eclipse, compile only dependencies are not exported via project dependencies. With this in mind, compile only dependencies are not inherited by the test classpath. The intention is that tests, like any other runtime environment, should provide their own implementation, either in the form of mocks or some other dependency. See the original article here.
