{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"scyjava does not agree with jgo on default m2 repo path","articleBody":"As reported [downstream in PyImageJ](https://github.com/imagej/pyimagej/issues/278#issuecomment-2508087482), scyjava sets the `m2_repo` to `~/.m2/repository` by default. Although you can override it using `scyjava.config.set_m2_repo`, the upstream jgo library has a function `jgo.m2_path` which does as follows:\r\n```python\r\ndef m2_path():\r\n    return os.getenv(\"M2_REPO\", (pathlib.Path.home() / \".m2\").absolute())\r\n```\r\nIn other words: it looks also at the `M2_REPO` environment variable, before falling back to `~/.m2`.\r\n\r\nThis behavior in jgo is actually *wrong* because `M2_REPO` is supposed to point to the actual local Maven repository cache directory e.g. `~/.m2/repository`, *not* the parent `~/.m2`. So a fix is needed in jgo; see also scijava/jgo#99 which covers essentially the same issue for `M2_HOME`. Probably the `m2_path` function should be deprecated in favor of two functions `m2_home` and `m2_repo` instead.\r\n\r\nAnd then what scyjava should do is ask jgo—once jgo yields the correct answer—what its default should be, so that it matches.","author":{"url":"https://github.com/ctrueden","@type":"Person","name":"ctrueden"},"datePublished":"2024-11-29T20:48:36.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/69/scyjava/issues/69"}
