maven-release-plugin causes mercurial scm provider to fail when only a module is released

Olivier Lamy added a comment - 18/Mar/11 5:03 PM probably a stupid issue fix with this commit http://svn.apache.org/viewvc?view=revision&revision=1083086 I have deployed a new Scm SNAPSHOT can you try again ?

Andreas Ebbert-Karroum added a comment - 05/Sep/11 10:28 AM Hi, I haven't tried it, but I doubt that this change is fixing everything that I described on the mailing list. Step 1 So, I started with a very simple multi-module project (/pom.xml and /multi/pom.xml) and tried to release just a single module (multi). It turned out that this is not possible, because during the release:perform phase, the whole hg repository is checked out, and the build is started in the root of that repository. => Use the latest maven-release-plugin:2.2-SNAPSHOT in which MRELEASE-457 < http://jira.codehaus.org/browse/MRELEASE-457 >is fixed. Step 2 The new dependencies with the snapshot release plugin also updates to a newer hg scm provider. The new hg scm provider has the interesting new habit to throw an exception, when you want to tag something, which does not concern the whole repository. Caused by: org.apache.maven.scm.ScmException: This provider doesn't support tagging subsets of a directory at org.apache.maven.scm.provider.hg.command.tag.HgTagCommand.executeTagCommand(HgTagCommand.java:77) at org.apache.maven.scm.command.tag.AbstractTagCommand.executeCommand(AbstractTagCommand.java:81) at org.apache.maven.scm.command.AbstractCommand.execute(AbstractCommand.java:59) ... 29 more => Update the dependencies of maven-release-plugin:2.2-SNAPSHOT to use maven-scm-provider-hg:1.4 Step 3 The next step was to move the parent pom out of the root of the hg repository. We have a standardized layout in our hg repositories (to take into account various tradeoffs between maven, m2eclipse, hudson, etc.) that we have all projects in directories under the root directory. So I tried to have / root / pom.xml (having a module ../multi) and / multi / pom.xml (having a parent ../root) The release plugin did not like that at all: [INFO] EXECUTING: cmd.exe /X /C "hg commit --message " [maven-release-plugin] prepare release root-1.6" C:\Temp\releasetest\parent\pom.xml C:\Temp\releasetest\multi\pom.xml" [INFO] EXECUTING: cmd.exe /X /C "*hg push file:///C:/Temp/releasetestrepo* " [INFO] Tagging release with the label root-1.6... [INFO] EXECUTING: cmd.exe /X /C "hg tag --message " [maven-release-plugin] copy for tag root-1.6" root-1.6" [INFO] EXECUTING: cmd.exe /X /C "*hg push file:///C:/Temp* " [ERROR] EXECUTION FAILED Execution of cmd : push failed with exit code: -1. Working directory was: c:\temp\releasetest Your Hg installation seems to be valid and complete. Hg version: 1.6.2 (OK) This is probably a bug, but I have no idea if this is in the scm provider, release plugin, shared components, ... I'm glad to create a jira issue for it, but would like to do so for the right project. => Having no pom.xml in the root of the repository is apparently a bad idea. But we need to have our "parent" in a folder under the root directly. So I created a thin dummy pom, which just has the real parent as module. Step 4 So we now have: / pom.xml / parent / pom.xml / multi / pom.xml While I created the root pom.xml, I tried to optimize a bit and included localCheckout=true to the plugin configuration, so that the tag checkout does not happen from the remote repository, but from the local one. Bad idea: [ERROR] Failed to execute goal org.apache.maven.plugins:maven-release-plugin:2.2-SNAPSHOT:perform (default-cli) on project root: The scm url is invalid. [ERROR] - An hg 'file' url must be on the form 'file:///' or 'file://localhost/'. My scm url is: scm:hg: file:///C:/Temp/releasetestrepo So also the "remote" hg repository is on the local filesystem, but when the local checkout occurs, the url is apparently not constructed correctly. => Ok, no localCheckout. Not a big deal, moving on. Step 5 If possible, I don't want the /parent/pom.xml to inherit from /pom.xml, because it may well be, that it needs to inherit from something completely different. I only wanted to use the /pom.xml as a forwarder to /parent/pom.xml. So I tried that, and tried to release the "multi"-module. I did this by running from working directory /parent the command "mvn --batch-mode -pl multi release:prepare". But I could not find a working scm configuration in /parent/pom.xml When it was set to "scm:hg: file:///C:/Temp/releasetestrepo/parent " I got this error - apperently it tried to replace the current module name "parent" in the scm url with "multi": [INFO] EXECUTING: cmd.exe /X /C "hg commit --message " [maven-release-plugin] prepare release multi-1.22" C:\Temp\releasetest\multi\pom.xml" [INFO] EXECUTING: cmd.exe /X /C "hg push * file:///C:/Temp/releasetestrepo/multi* " But when I set the scm url to the correct value "scm:hg: file:///C:/Temp/releasetestrepo " it removed the last path element: [INFO] EXECUTING: cmd.exe /X /C "hg commit --message " [maven-release-plugin] prepare release multi-1.22" C:\Temp\releasetest\multi\pom.xml" [INFO] EXECUTING: cmd.exe /X /C "hg push * file:///C:/Temp/multi* " ==> so apparently the /parent/pom.xml needs to inherit from /pom.xml and scm info should be in the root. Step 6 So I tried that but ran into problems again! C:\Temp\releasetest>mvn -pl multi --offline --batch-mode release:prepare [INFO] Checking in modified POMs... [INFO] EXECUTING: cmd.exe /X /C "hg commit --message " [maven-release-plugin] prepare release multi-1.28" C:\Temp\releasetest\multi\pom.xml" [INFO] EXECUTING: cmd.exe /X /C "hg push file:///C:/Temp/multi " [ERROR] EXECUTION FAILED Execution of cmd : push failed with exit code: -1. Working directory was: C:\Temp\releasetest\multi Your Hg installation seems to be valid and complete. Hg version: 1.6.2 (OK) => This means, the scm configuration has to be present in every module, even if it is absolutely the same everywhere. Step 7 So I got it working in an example project, but the fact, that I have to copy the scm configuration into every module, makes that solution impossible to rollout to any serious production environment. pom.xml <project xmlns= "http: //maven.apache.org/POM/4.0.0" xmlns:xsi=" http: //www.w3.org/2001/XMLSchema-instance " xsi:schemaLocation=" http: //maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>de.aek.test</groupId> <artifactId>root</artifactId> <version>1.12-SNAPSHOT</version> <packaging>pom</packaging> <modules> <module>parent</module> </modules> <scm> <connection>scm:hg:file: ///C:/Temp/releasetestrepo</connection> <developerConnection>scm:hg:file: ///C:/Temp/releasetestrepo</developerConnection> </scm> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-release-plugin</artifactId> <version>2.2-SNAPSHOT</version> <configuration> <allowTimestampedSnapshots> true </allowTimestampedSnapshots> <goals>install</goals> <resume> false </resume> </configuration> <dependencies> <dependency> <groupId>org.apache.maven.scm</groupId> <artifactId>maven-scm-provider-hg</artifactId> <version>1.4</version> </dependency> </dependencies> </plugin> </plugins> </build> <pluginRepositories> <pluginRepository> <id>apache.snapshots</id> <name>Apache Snapshots</name> <url>https: //repository.apache.org/content/groups/snapshots/ </url> </pluginRepository> </pluginRepositories> </project> /parent/pom.xml <project xmlns= "http: //maven.apache.org/POM/4.0.0" xmlns:xsi=" http: //www.w3.org/2001/XMLSchema-instance " xsi:schemaLocation=" http: //maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>de.aek.test</groupId> <artifactId>root</artifactId> <version>1.10</version> <relativePath>..</relativePath> </parent> <groupId>de.aek.test</groupId> <artifactId>parent</artifactId> <version>1.13-SNAPSHOT</version> <packaging>pom</packaging> <scm> <connection>scm:hg:file: ///C:/Temp/releasetestrepo</connection> <developerConnection>scm:hg:file: ///C:/Temp/releasetestrepo</developerConnection> </scm> <modules> <module>../multi</module> </modules> </project> /multi/pom.xml <project xmlns= "http: //maven.apache.org/POM/4.0.0" xmlns:xsi=" http: //www.w3.org/2001/XMLSchema-instance " xsi:schemaLocation=" http: //maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>de.aek.test</groupId> <artifactId>parent</artifactId> <version>1.12</version> <relativePath>../parent</relativePath> </parent> <groupId>de.aek.test</groupId> <artifactId>multi</artifactId> <version>1.27-SNAPSHOT</version> <packaging>pom</packaging> <scm> <connection>scm:hg:file: ///C:/Temp/releasetestrepo</connection> <developerConnection>scm:hg:file: ///C:/Temp/releasetestrepo</developerConnection> </scm> </project> preparing and performing a release C:\Temp\releasetest>mvn -pl multi --offline --batch-mode release:prepare [INFO] Scanning for projects...
