{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Local tests failing","articleBody":"### Most appropriate sub-area of Processing 4?\n\nUnit testing\n\n### Processing version\n\n4.3.4\n\n### Operating system\n\nMacOS, Windows, Linux\n\n### Bug description\n\nLocal testing is broken, creating a classpath issue with an an \"undefined\" module in gradle. Surprisingly, this **does not fail on github CI**. It does fail on windows, macos, (tested by me and my students) and linux (as tested by @catilac )\n\nThe issue was introduced in PR #1423\n\nThe issue appears to stem from Github changing their gradle version and @moon is working on a long-term solution to bring local testing into parity with PR #1459 (if I understood all this right)\n\n### Steps to reproduce this\n\nCheck out main branch. Try to run tests:\n```\n\u003e ./gradlew clean\n\u003e ./gradlew test\n```\n\nWill see:\n```\n\u003e Task :java:gradle:test\n\nProcessingPluginTest \u003e testJavaSourceFile FAILED\n    org.gradle.testkit.runner.UnexpectedBuildFailure at ProcessingPluginTest.kt:34\n\nProcessingPluginTest \u003e testImportingLibrary FAILED\n    org.gradle.testkit.runner.UnexpectedBuildFailure at ProcessingPluginTest.kt:34\n\nProcessingPluginTest \u003e testSinglePDE FAILED\n    org.gradle.testkit.runner.UnexpectedBuildFailure at ProcessingPluginTest.kt:34\n\nProcessingPluginTest \u003e testMultiplePDE FAILED\n    org.gradle.testkit.runner.UnexpectedBuildFailure at ProcessingPluginTest.kt:34\n\nProcessingPluginTest \u003e testWithUnsavedSource FAILED\n    org.gradle.testkit.runner.UnexpectedBuildFailure at ProcessingPluginTest.kt:34\n\n7 tests completed, 5 failed\n\n\u003e Task :java:gradle:test FAILED\n\nFAILURE: Build failed with an exception.\n\n* What went wrong:\nExecution failed for task ':java:gradle:test'.\n\u003e There were failing tests. See the report at: file:///Users/shermanm/git/processing4/java/gradle/build/reports/tests/test/index.html\n\n* Try:\n\u003e Run with --scan to get full insights.\n\nBUILD FAILED in 7s\n66 actionable tasks: 2 executed, 64 up-to-date\n```\nDiving into the report link, you'll find the modules all fail:\n\n- ProcessingPluginTest. testImportingLibrary\n- ProcessingPluginTest. testJavaSourceFile\n- ProcessingPluginTest. testMultiplePDE\n- ProcessingPluginTest. testSinglePDE\n- ProcessingPluginTest. testWithUnsavedSource\n\n\u003cimg width=\"708\" height=\"514\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/dee6fd9a-e10a-41b5-a628-e25687d20b16\" /\u003e\n\nClicking into their reports, they fail with the same core issue in the middle: `Could not resolve all files for configuration ':compileClasspath'. Could not find org.processing:core:unspecified.` \n\nHere's one full report:\n```\norg.gradle.testkit.runner.UnexpectedBuildFailure: Unexpected build execution failure in

:\n```\n821d62c5e43b8e4e72aa2cb4fae56d092ef98c94 is the first bad commit\ncommit 821d62c5e43b8e4e72aa2cb4fae56d092ef98c94\nAuthor: Stef Tervelde \u003cstef@steftervelde.nl\u003e\nDate:   Tue Feb 10 01:25:49 2026 +0100\n\n    Write and load version.properties for plugin (#1423)\n    \n    Add a writeVersion Gradle task that writes project.version to build/resources/main/version.properties, so the plugin can access the project version at runtime. This way the version number of the plugin and the used version of processing.core will be the same.\n\n java/gradle/build.gradle.kts                    | 12 ++++++++++++\n java/gradle/src/main/kotlin/ProcessingPlugin.kt |  5 ++++-\n 2 files changed, 16 insertions(+), 1 deletion(-)\n```\nThis was written by @Stefterv . I'll reproduce the conversation from the discord below.\n\n### snippet\n\n_No response_\n\n### Additional context\n\nThis was discussed in the Discord devs-chat channel. Reproduced here to not be forgotten!\n\n@Stefterv\n\u003e Ah the Gradle Plugin uses the local version of org.processing:core:unspecified to run tests, which seems to not have been build/referenced. I suspected a missing dependency on one of the required gradle tasks\n\n@Stefterv \n\u003e Oh lovely `:core` needs to be signed for that to work\n\u003e And we don't do signing in tests for obv reasons\n\u003e Also the published gradle plugins disappeared from their verification so I suspect there should've been an email on the processing-bot email about why \n\n### Would you like to work on the issue?\n\nI’m not sure yet","author":{"url":"https://github.com/marksherman","@type":"Person","name":"marksherman"},"datePublished":"2026-03-16T19:13:03.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/1485/processing4/issues/1485"}
