My problem: versions-maven-plugin helps me to up version in some module (let's call it A) in my multi-module maven project.
Some modules (let's call it B and C) in this project have in dependencies module A. I need to up versions for this modules (B and C) too. Sometimes, i also need to up version in other module (B-parent) where B (or C) in dependencies (A version up -> B version up -> B-parent version up). Other problem is the modules can be at different levels of nesting.
Example:
root:
---B-parent:
---B (A in dependencies)
---C-parent
---C (A in dependencies)
---A-parent:
---A
Process: A version up -> A-parent version up, C version-up -> C-parent version-up, B version-up -> B-parent version up.
This plugin can't do this.
Is there any idea how this can be done?
Or my strategy of updating versions is not good enough?
I've made a script for increasing version numbers in all dependent modules recursively with a versions-maven-plugin.
Algorithm is as follows:
Run versions:set in target module
Run versions:set in all modules which have been updated by versions:set from previous step. If the module has been already processed - skip it.
Repeat step 2
Python 2.7 code
#!/usr/bin/env python
# -*- coding: utf-8 -*- #
# How To
#
# Run script and pass module path as a first argument.
# Or run it without arguments in module dir.
#
# Script will request the new version number for each module.
# If no version provided - last digit will be incremented (1.0.0 -> 1.0.1).
# cd <module-path>
# <project-dir>/increment-version.py
# ...
# review changes and commit

java: openjdk version "19.0.1" 2022-10-18
scala: 2.13.10
Apache Lucene: 9.4.2
I took the Lucene documentation example and convert it to Scala program:
package test
import org.apache.lucene.analysis.standard.StandardAnalyzer
import org.apache.lucene.document.{Document, Field, TextField}
import org.apache.lucene.index.{DirectoryReader, IndexWriter, IndexWriterConfig}
import org.apache.lucene.queryparser.classic.QueryParser

import java.nio.file.{Files, Path}
object Test extends App {
val analyzer: StandardAnalyzer = new StandardAnalyzer()
val indexPath: Path = Files.createTempDirectory("tempIndex")
val directory: FSDirectory = FSDirectory.open(indexPath)
val config: IndexWriterConfig = new IndexWriterConfig(analyzer)
val iwriter: IndexWriter = new IndexWriter(directory, config)
val doc: Document = new Document()
val text: String = "This is the text to be indexed."
doc.add(new Field("fieldname", text, TextField.TYPE_STORED))
iwriter.addDocument(doc)
iwriter.close()
// Now search the index:
val ireader: DirectoryReader = DirectoryReader.open(directory)
val isearcher: IndexSearcher = new IndexSearcher(ireader)
// Parse a simple query that searches for "text":
val parser: QueryParser = new QueryParser("fieldname", analyzer)
val query: Query = parser.parse("text")
val hits: Array[ScoreDoc] = isearcher.search(query, 10).scoreDocs
assert (hits.length == 1)
// Iterate through the results:
for (i <- hits.indices) {
val hitDoc = isearcher.doc(hits(i).doc)
assert("This is the text to be indexed.".equals(hitDoc.get("fieldname")))
}
ireader.close()
directory.close()
println("The end!")
}
If I use the following sbt file:
ThisBuild / version := "0.1.0-SNAPSHOT"
ThisBuild / scalaVersion := "2.13.10"
lazy val root = (project in file("."))
.settings(
name := "Test"
)
val luceneVersion = "9.4.2"
libraryDependencies ++= Seq(
"org.apache.lucene" % "lucene-core" % luceneVersion,
"org.apache.lucene" % "lucene-queryparser" % luceneVersion
)
The compilation gives me the error:
[error] Deduplicate found different file contents in the following:
[error] Jar name = lucene-core-9.4.2.jar, jar org = org.apache.lucene, entry target = module-info.class
[error] Jar name = lucene-queries-9.4.2.jar, jar org = org.apache.lucene, entry target = module-info.class
[error] Jar name = lucene-queryparser-9.4.2.jar, jar org = org.apache.lucene, entry target = module-info.class
[error] Jar name = lucene-sandbox-9.4.2.jar, jar org = org.apache.lucene, entry target = module-info.class
So I included in the sbt file:
assembly / assemblyMergeStrategy := {
case PathList("META-INF", xs # _*) => MergeStrategy.discard
case _ => MergeStrategy.first
}
After that the compilation and execution of the program were ok:
sbt "runMain test.Test"
But if I want to create a fat jar file and execute it, I got the following exception:

So, what did I do wrong?
Thanks.
case PathList("META-INF", xs # _*) => MergeStrategy.discard means that you're ignoring all META-INF directories (the whole their content). This is dangerous. The dependencies lucene-core and lucene-sandbox have service files in their META-INF. You should be more selective in what you ignore. Try to ignore only Java 9+ files module-info.class
assembly / assemblyMergeStrategy := {
case x if x.endsWith("module-info.class") => MergeStrategy.discard
case x =>
val oldStrategy = (assembly / assemblyMergeStrategy).value
oldStrategy(x)
}
or at least unignore META-INF/services subdirectories
assembly / assemblyMergeStrategy := {
case PathList("META-INF", "services", xs # _*) => MergeStrategy.concat
case PathList("META-INF", xs # _*) => MergeStrategy.discard
case _ => MergeStrategy.first

I am using Bazel as the build tool for my Java project. I have JDK 11 installed on my mac, but Bazel uses Java 8 to build the binaries. Does anyone know how I could change this?
BUILD.bazel
java_binary(
name = 'JavaBinary',
srcs = ['JavaBinary.java'],
main_class = 'JavaBinary',
)
load(
"#bazel_tools//tools/jdk:default_java_toolchain.bzl",
"default_java_toolchain",
)
default_java_toolchain(
name = "default_toolchain",
visibility = ["//visibility:public"],
)
JavaBinary.java
public class JavaBinary {
public static void main(String[] args) {
System.out.println("Successfully executed JavaBinary!");
System.out.println("Version: " + System.getProperty("java.version"));
}
}
WORKSPACE.bazel
load("#bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
name = "rules_java",
sha256 = "220b87d8cfabd22d1c6d8e3cdb4249abd4c93dcc152e0667db061fb1b957ee68",
url = "https://github.com/bazelbuild/rules_java/releases/download/0.1.1/rules_java-0.1.1.tar.gz",
)
load("#rules_java//java:repositories.bzl", "rules_java_dependencies", "rules_java_toolchains")
rules_java_dependencies()
rules_java_toolchains()
Run it this way:
bazel run :JavaBinary \
--java_toolchain=:default_toolchain \
--javabase=#bazel_tools//tools/jdk:remote_jdk11
You can also create .bazelrc file an then execute bazel run :JavaBinary:
.bazelrc
build --java_toolchain=:default_toolchain
build --javabase=#bazel_tools//tools/jdk:remote_jdk11
I'm using Python to visualize a graph through a tool named wot using jupyter notebook. It utilizes Gephi, a java-based graph utility. I try to run function to return coordinate output files as below:

I can found "GraphLayout.java" and "gephi-toolkit-0.9.2-all.jar" files in the path, so I really don't know why it can't be loaded.
Do you have any suggestions?

I am trying to gather data from jenkins using groovy script and getting an error:
unable to resolve class com.cloudbees.hudson.plugins.folder.Folder
Below is the code:
import jenkins.model.*
import hudson.model.*
import groovy.time.TimeCategory
use ( TimeCategory ) {
// e.g. find jobs not run in last 1 year
sometimeago = (new Date() - 1.year)
}
jobs = Jenkins.instance.getAllItems()
lastabort = null
jobs.each { j ->
if (j instanceof com.cloudbees.hudson.plugins.folder.Folder) { return }
numbuilds = j.builds.size()
if (numbuilds == 0) {
println 'JOB: ' + j.fullName
println ' -> no build'
return
}
lastbuild = j.builds[numbuilds - 1]
if (lastbuild.timestamp.getTime() < sometimeago) {
println 'JOB: ' + j.fullName
println ' -> lastbuild: ' + lastbuild.displayName + ' = ' + lastbuild.result + ', time: ' + lastbuild.timestampString2
}
}
The error is:
rg.codehaus.groovy.control.MultipleCompilationErrorsException:
startup failed: Script1.groovy: 12: unable to resolve class
com.cloudbees.hudson.plugins.folder.Folder # line 12, column 20. if (j

error at
org.codehaus.groovy.control.ErrorCollector.failIfErrors(ErrorCollector.java:302)
I see Folder.java in jenkinsci/cloudbees-folder-plugin.
That means you need to:
check if you do have JENKINS/CloudBees Folders Plugin installed, or your groovy script would not be able to resolve that dependency.
Add "import com.cloudbees.hudson.plugins.folder.*" to be sure the script is able to make the instanceOf work.
When running groovy scripts that import libraries in Jenkins, check that your Jenkins build step is an "Execute system Groovy script", not a plain old "Execute Groovy script".
The 'system' scripts run on the existing JVM, as opposed to spawning a new one and therefore losing access to the shared libraries available to the original Jenkins JVM instance.

I've put together a proof of concept which aims to provide a skeleton SBT multimodule project which utilizes DataNucleus JDO Enhancer with mixed Java and Scala sources.
The difficulty appears when I try to enhance persistence classes from SBT. Apparently, I'm not passing the correct classpath when calling Fork.java.fork(...) from SBT.
See also this question:
How can SBT generate metamodel classes from model classes using DataNucleus?

Then you need to wire DataNucleus Enhancer as part of your build process. This is done via manipulateBytecode sub-task, as demonstrated below:
lazy val model =
project.in(file("model"))
// .settings(publishSettings:_*)
.settings(librarySettings:_*)
.settings(paranoidOptions:_*)
.settings(otestFramework: _*)
.settings(deps_tagging:_*)
//-- .settings(deps_stream:_*)
.settings(deps_database:_*)
.settings(
Seq(
// This trick requires SBT 0.13.8
manipulateBytecode in Compile := {
val previous = (manipulateBytecode in Compile).value
sbtRunner( // javaRunner also works!
mainClass = "javax.jdo.Enhancer",
args =
Seq(
"-v",
"-pu", "persistence-h2",
"-d", (classDirectory in Compile).value.absolutePath),
classpath =
(managedClasspath in Compile).value.files ++
(unmanagedResourceDirectories in Compile).value :+
(classDirectory in Compile).value,
cwd = (classDirectory in Compile).value,
javaHome = javaHome.value,
envVars = (envVars in Compile).value
)
previous
}
):_*)
.dependsOn(util)
For a complete example, including a few JDO annotated persistence classes and some rudimentary test cases, please have a look at

I think the issue is you're passing your dependency jars as boot jars not as the classpath.
From your poc project perhaps something like:
val jvm_ = runJVMOptions.map(p => p.toString) ++
Seq("-cp", cp_ mkString java.io.File.pathSeparator)
