I am using Buildr as my build tool. Part of my build process generates Java source from a WSDL using JAX-WS. I have an ANT build script that does this with the wsimport ant task. Using the AntWrap Ruby module in Buildr I can do the same thing.
My problem is I am getting the OutOfMemoryError PermGen space when trying to generate source for many WSDL's. I got the same problem when running Ant by itself but resolved it by setting the ANT_OPTS environment variable to:
set ANT_OPTS=-Xmx512m -XX:PermSize=64m -XX:MaxPermSize=128m
But when I run my build using Buildr I still get the error even though this environment variable is set. I have even tried setting this variable in my build file but this hasn't helped.
My environment is as follows:
windows XP
JRuby 1.6.3
Buildr 1.4.6
AntWrap 0.7.0
Did you try setting JAVA_OPTS in the buildfile, I am not sure if buildr/antwrap picks up the ANT_OPS environment variables.
ENV['JAVA_OPTS'] ||= '-Xms1g -Xmx1g'

I would like to analyse a simple java project for testing sonarQube installation.
However when i run sonar-runner. bat i have this error.
It seems that your Java installation is not correct. You should test the value of JAVA_HOME variable by executing Get-Item Env:JAVA_HOME in PowerShell and verify that it points to a valid Java installation.
Alternatively, you can download sonar-scanner for Windows which already includes Java runtime.
Intellij is giving me errors all around for brand new kotlin/spring project and I cannot build or run the project from the IDE.
If I do it from the command line however, there are no issues and I can build and run the app.
'classpath' in 'org.gradle.api.artifacts.dsl.DependencyHandler' cannot be applied to '(groovy.lang.GString)'
'apply' in 'org.gradle.api.plugins.PluginAware' cannot be applied to '(['plugin':java.lang.String])'
Cannot access class 'java.lang.String'. Check your module classpath for missing or conflicting dependencie
Type mismatch.
Required:
java.lang.String
Found:
kotlin.String
Any ideas to what may be the issue?
I tried Kotlin multiplatform JVM type mismatch in InteliJ but doesn't seem to fix the issue.
UPDATE:
Cleared gradle caches, reinstalled Intellij, Import project that was created from start.spring.io with Gradle and Kotlin selected.
Using default gradle wrapper and project jdk (the path says jre)? gives me an error. Open gradle settings just opens the file explorer.
Using default gradle wrapper and machine local JDK same issues with the dependencies from above.
This issue comes up if you set up your own module inside IntelliJ and you think that since you are doing a Kotlin (Maven) project, the SDK should be set to Kotlin. Wrong!
The problem is shown in the first image. The project SDK is set to Kotlin.
Change it to Java. Probably any 8+ Java will be good enough.
This solves the IDE errors and the compiler errors as well.
Unset KOTLIN_HOME and other Kotlin- or Java-related settings you may have in your environment (env to check, unset NAME to unset.)
Then kill any Gradle daemon still running (pkill -f GradleDaemon) and test your Gradle build from the terminal. If all goes well, remove the .idea directory; restart IDEA, making sure to run it without the stray environment variables (for example, launch idea.sh from the terminal where you unset them); and re-import your project, with the choice of using the default Gradle wrapper.
If you need to use standalone Kotlin versions, installed for example through SDKMAN, consider taking the SDKMAN activation lines out of your shell init file (.bashrc for Bash) and into a standalone script (say, ~/bin/sdkman) that will also change your shell prompt (PS1 in Bash) to remind you that you have entered a SDKMAN-managed CLI session.
I have feature files in cucumber ,for its step definition I am using Ruby-selenium.I am trying to integrate with my local Jenkins but I am unable to do the same.
Any headsup how to proceed
When things about Jenkins, it is mostly about Environment Variables. I recommend you to check if your local env vars are correctly passed to Jenkins.
I want specify the Java home path during building my Android gradle via command line; for example,
gradle build -d path of jdk
Is it possible?
According to gradle documentation:
The following properties can be used to configure the Gradle build
environment:
...
org.gradle.java.home Specifies the Java home for the Gradle build
process. The value can be set to either a jdk or jre location,
however, depending on what your build does, jdk is safer. A reasonable
default is used if the setting is unspecified.
org.gradle.jvmargs Specifies the jvmargs used for the daemon process.
The setting is particularly useful for tweaking memory settings. At
the moment the default settings are pretty generous with regards to
memory.
In other words, you can do it simply by running
gradle build -Dorg.gradle.java.home=<java home path>
Depending on what you want to accomplish, one of the following should work.
As Amnon Shochot suggested, set the -Dorg.gradle.java.home flag. This is probably preferable in most cases.
If you want to have use a particular JDK throughout, set the JAVA_HOME variable appropriately before executing gradle.
$ export JAVA_HOME=/usr/local/specialJava/
$ gradle build
If you don't want to change the environment, try adding the below to your build.gradle script. It should affect only the compiler used to compile Java code, nothing else. So Gradle doesn't run inside this particular JDK, but it will use it for compiling.
tasks.withType(JavaCompile) {
options.fork = true
options.forkOptions.executable = "/usr/local/specialJava/bin/javac"
}
(Last option stolen from here)
Scenario
While using the Maven Ant Task artifact:deploy, I'm encountering the error java.lang.OutOfMemoryError: Java heap space.
I'm only getting the error if the size of the file being deployed is greater than 25 MB. My artifacts are not greater than 50 MB in size.
What could the reason be? And, what can I do to fix it?
Code snippet
<artifact:deploy file="#{app.name}.jar">
<pom file="#{pom.file}"/>
<remoteRepository url="http://xxx.com:xxx/xxx-webapp/content/repositories/xxx-releases/">
<authentication username="xxx" password="xxx" />
</remoteRepository>
</artifact:deploy>
Existing solutions
Most online results indicate that it's something to do with the JVM default heap size and that it can be fixed by setting the appropriate environmental variables.
However, I would want the Ant scripts to run on any computer and not to depend on the environmental variables.
Is there a way to configure these settings in the Ant scripts or the
POM file?
EDIT
The install-provider task (http://maven.apache.org/ant-tasks/examples/install-deploy.html) seems to work for some people. I keep getting download errors when I use it.
Answer
It turns out that I'm not getting the Java heap error when I run my Maven Ant task on a different machine (which probably has more memory allocated to the JVM heap). Hence, I haven't attempted the solution mentioned by #Attila, though it seems to be going in the right direction.
Once ant is running, you cannot change the heap size of the JVM runing ant. So your only option is to run the task that comsumes a large amount of memory in a separate JVM, specifying enough heap space. Note this relies on the task allowing you to fork a new JVM to execute the task
Update: I could not find a way to specify to fork the maven (deploy) task, but this page specifies how you can define a macro to run maven using the java task (note that this relies on maven beeing installed and properly configured on the machine) (see the "Using the Java Task" section)
please try to increase VM memory, eg.: -Xmx512m
if you are using ANT, you can add it to the ANT_OPTS environment variable: ANT_OPTS="-Xmx512m"
