Summary: 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 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)
