Claes Nordmark commented on MSOURCES-119: ----------------------------------------- I've checked and java version seems to be irrelevant at least. Tried with both java 8 and java 11. Different maven versions have been tested as well, 3.2.1 and 3.5.4. I've raised another ticket on plexus archiver, which could be something to take as input: [https://github.com/codehaus-plexus/plexus-archiver/issues/105] > Archiving to jar is very slow > ----------------------------- > > Key: MSOURCES-119 > URL: https://issues.apache.org/jira/browse/MSOURCES-119 > Project: Maven Source Plugin > Issue Type: Bug > Affects Versions: 3.0.0 > Environment: RedHat 7 > Reporter: Claes Nordmark > Priority: Major > > Doing a stackdump while "maven-source-plugin:3.0.0:jar-no-fork > (attach-sources)" shows thread spending a lot of time in > UnixNativeDispatcher.getgrgid. > This was not visible in java 8 and source plugin version 2.4. > Our previous build time has been increased from 5min to 3h 30min. > Tested version Java 11 and 3.0.0 of maven-source-plugin > maven config: > {code:java} > <plugin> > <groupId>org.apache.maven.plugins</groupId> > <artifactId>maven-source-plugin</artifactId> > <version>3.0.0</version> > <executions> > <execution> > <id>attach-sources</id> > <goals> > <goal>jar-no-fork</goal> > </goals> > </execution> > </executions> > </plugin>{code} > {{java.lang.Thread.State: RUNNABLE}} > {{ at sun.nio.fs.UnixNativeDispatcher.getgrgid(java.base@11/Native Method)}} > {{ at > sun.nio.fs.UnixUserPrincipals.fromGid(java.base@11/UnixUserPrincipals.java:129)}} > {{ at > sun.nio.fs.UnixFileAttributes.group(java.base@11/UnixFileAttributes.java:208)}} > {{ - locked <0x00000006b0773fd8> (a sun.nio.fs.UnixFileAttributes)}} > {{ at > sun.nio.fs.UnixFileAttributeViews$Posix.addRequestedPosixAttributes(java.base@11/UnixFileAttributeViews.java:214)}} > {{ at > sun.nio.fs.UnixFileAttributeViews$Unix.readAttributes(java.base@11/UnixFileAttributeViews.java:362)}} > {{ at > sun.nio.fs.AbstractFileSystemProvider.readAttributes(java.base@11/AbstractFileSystemProvider.java:94)}} > {{ at java.nio.file.Files.readAttributes(java.base@11/Files.java:1996)}} > {{ at > org.codehaus.plexus.components.io.attributes.Java7FileAttributes.<init>(Java7FileAttributes.java:65)}} > {{ at > org.codehaus.plexus.components.io.resources.PlexusIoFileResourceCollection.addResourcesJava7(PlexusIoFileResourceCollection.java:192)}} > {{ at > org.codehaus.plexus.components.io.resources.PlexusIoFileResourceCollection.getResources(PlexusIoFileResourceCollection.java:287)}} > {{ at > org.codehaus.plexus.archiver.AbstractArchiver$1.hasNext(AbstractArchiver.java:504)}} > {{ at > org.apache.maven.plugins.source.AbstractSourceJarMojo.packageSources(AbstractSourceJarMojo.java:287)}} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
