CI-server (Hudson), for which I am responsible, builds Maven project. After the last commit, the build failed:
[INFO] -------------------------------------------------------------

Required class (com.sun.xml.internal.messaging.saaj.packaging.mime.util.BASE64EncoderStream) is situated in rt.jar.
I tried (In accordance with the instructions at http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#System_Dependencies) to add system dependency in project's pom.xml:
<dependency>
<groupId>dummy</groupId>
<artifactId>dummy</artifactId>
<version>1</version>
<scope>system</scope>
<systemPath>${java.home}/lib/rt.jar</systemPath>
</dependency>
It did not help.
The most interesting is that all files compiled fine on the local machine of my collegue (he use Eclipse build-in compiler).
In internet I found the same question (link: http://maven.40175.n5.nabble.com/Why-can-t-Maven-find-com-sun-xml-internal-messaging-saaj-util-ByteOutputStream-class-td107361.html). The last answer was that the reason for this trouble is Oracle's Java compiler.
So, I changed Oracle's jdk to OpenJDK, but it did not help.
Does someone have any suggestions on how to solve this problem?
Need to specify -XDignore.symbol.file and add rt.jar dependency and <fork>true</fork> as the compiler plugin will otherwise silently drop any -XD flags: e.g.
...
<dependency>
<groupId>groupid</groupId>
<artifactId>artifiactId</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${java.home}/lib/rt.jar</systemPath>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.3</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
<compilerArgs>
<arg>-XDignore.symbol.file</arg>
</compilerArgs>
<fork>true</fork>
</configuration>
...
The missing class seems to be JRE internal (as indicated in its namespace), and should not be referenced from your code. It is probably only available on specific platforms or JRE versions.
Consider replacing it with another Base64 encoder class, e.g. one from the Apache Commmons Codec project.
Java 8 update
Java 8 finally introduced a Base64 class in the public part of the JDK: java.util.Base64.

I have a project in which I want to use classes generated by ANTLR4 in a piece of Kotlin code.
In pom.xml, ANTLR4 is configured as follows.
<dependencies>
<dependency>
<groupId>org.antlr</groupId>
<artifactId>antlr4-runtime</artifactId>
<version>4.7.1</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.antlr</groupId>
<artifactId>antlr4-maven-plugin</artifactId>
<version>4.7.1</version>
<executions>
<execution>
<goals>
<goal>antlr4</goal>
</goals>
</execution>
</executions>
</plugin>
The generated classes are put into target/generated-sources/antlr4:
mvn clean package, mvn clean assembly, as well as rebuilding the project in Idea lead to the following error:
Note that the errors occur only in the Kotlin class Transpiler.kt, but not in the test.
How can I fix this (make sure that classes generated by ANTLR4 can be used in Kotlin code)?
Update 1: After moving the grammar file as suggested by #Bart Kiers and executing mvn clean antlr4:antlr4, the errors in Idea disappeared. However mvn clean antlr4:antlr4 install still results in build errors:
[ERROR] Failed to execute goal org.jetbrains.kotlin:kotlin-maven-plugin:1.4.21:compile (compile) on project elispt: Compilation failure: Compilation failure:
[ERROR] /Users/dp118m/dev/misc/elispt/src/main/kotlin/com/dpisarenko/deplorable/Transpiler.kt:[9,21] Unresolved reference: DeplorableLexer

[ERROR] /Users/dp118m/dev/misc/elispt/src/main/kotlin/com/dpisarenko/deplorable/Transpiler.kt:[12,21] Unresolved reference: DeplorableParser
It should work if you do the following:
move Deplorable.g4 to src/main/antlr4/com/dpisarenko/deplorable/ (note that you placed it inside src/main/antlr4/com.dpisarenko.deplorable/!)
run mvn clean antlr4:antlr4
if not already done, mark target/generated-sources/antlr4 as the "Generated Sources Root" (right click it in your IDE and select Mark Directory as)
If not, try using the latest ANTLR4 version: 4.9.1 (not just the tool and runtime, but also for antlr4-maven-plugin).
I'm quite new to Maven so apologies upfront. I'm attempting to build my application which I had previously written and built in Eclipse with no issues. I've attempted to convert the project to Maven structure and create a pom.xml file bu when I try to build the project I get Compilation Errors on all of the environment methods I have used. The output from attempting to build is as follows:

Thanks in advance!
You can either create from the beginning a maven project in eclipse, or mavenize it after creation as a regular java project (right click on the eclipse project "convert to maven") -- if you have you installed the maven plugin (m2e). Make sure you clean and build.
Also, it seems that you are using on your system java8 (Java version: 1.8.0_51, vendor: Oracle Corporation), but in the pom you configure your maven-compliler-plugin to target JRE of version 1.7. Make sure you have this version installed, and path configured in eclipse (project properties-->java build path).
Do you have various modules in your maven project? pluginManagement is only a way to share the same plugin configuration across all your project modules. You would need to put the maven-compiler-plugin in plugins as well.
The solution involved changing the android version being used to 4.2.
My project uses sun.security.tools.keytool to generate certificate under JDK 1.8 and this package can be found in rt.jar. According to Introduction to the Dependency Mechanism, System Dependencies, I can add rt.jar as a dependency to my project:
<dependency>
<groupId>sun.jdk</groupId>
<artifactId>rt.jar</artifactId>
<version>1.8</version>
<scope>system</scope>
<systemPath>${java.home}/lib/rt.jar</systemPath>
</dependency>
I'm pretty sure Maven found this jar file. However when I import sun.security.tools.keytool.Main, it still generates an error. Moreover, the most strange thing is if I copy rt.jar into someplace and fill its path in pom.xml, it works! As soon as I switch back to use the original rt.jar, it fails!
Can anyone tell me how could this happen?
I created a Maven project and added the <dependency> of your question to its POM.
First I got:
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] .../SO-31353565/src/main/java/igb/so/SO31353565.java:[6,34]
package sun.security.tools.keytool does not exist
[ERROR] .../SO-31353565/src/main/java/igb/so/SO31353565.java:[12,50]
cannot find symbol
symbol: variable Main
location: class igb.so.SO31353565
Then, according to Cannot find symbol (CertAndKeyGen) with JDK8, I added:
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.2</version>
<configuration>
<fork>true</fork>
<compilerArgument>-XDignore.symbol.file</compilerArgument>
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>
to the POM and the compilation succeeded.
If you are using Gradle instead of Maven you can add this to your build:
compileJava {
options.fork = true
options.forkOptions.executable = 'javac'
options.compilerArgs << "-XDignore.symbol.file"
}
It worked for me! ;)
I solved it like this:
Add to JAVA_HOME/lib/rt.jar
Go to Eclipse Menu Windows -> Windows -> Preferences -> Java -> Installed JREs
Select jdk version. In me case jdk-11.0.4
Select Add External JARs.. and add JAVA_HOME/lib/rt.jar
I am deploying webapp to the openshift cloud.
While compiling the resources by maven automatically after deploying, it shows Base64: symbol not found
However when I maven compile it on my Pc, their are no errors and build is successfull. I tried to change Base64 from java.util to apache.commons.codecs. The error is still there while deploying and it successfully runs at my local machine
Following is the pom.xml
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.5.1</version>
<inherited>true</inherited>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
</plugins>
<dependencies>
<dependency>
<groupId>commons-codec</groupId>
<artifactId>commons-codec</artifactId>
<version>1.4</version>
</dependency>
Should I place the commons-codec jar in WEB_INF directory. i read the solution somewhere but was not sure about it.
please suggest a solution. Thank you
</dependencies>
My guess is that you're using JDK 8 on your machine, but JDK 7 where the error is happening as java.util.Base64 is only available since Java SE 8.
I recommend to use the same Java version on both machines.
Otherwise you should consider cross-compiling. Just setting the source and target level is not enough, as you can see, as you're still able to call new APIs.
I am trying to convert a project from compiling with Java 6 to Java 8. We are using the webstart-maven-plugin for which there is currently a workaround (http://mojo.10943.n7.nabble.com/jira-MWEBSTART-269-Java-8-support-td44357.html) for compiling with Java 8 by adding the following dependencies to the plugin definition.
...
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>webstart-maven-plugin</artifactId>
<version>1.0-beta-6</version>
<dependencies>
<dependency>
<groupId>org.codehaus.mojo</groupId>
<artifactId>webstart-pack200-impl</artifactId>
<version>1.0-beta-6</version>
</dependency>
<dependency>
<groupId>org.codehaus.mojo</groupId>
<artifactId>keytool-api-1.7</artifactId>
<version>1.4</version>
</dependency>
</dependencies>
...
</plugin>
</plugins>
</pluginManagement>
</build>
...
This got me past my initial issues.
I am now receiving the following error.
[ERROR] Failed to execute goal org.codehaus.mojo:webstart-maven-plugin:1.0-beta-6:jnlp-inline (default) on project <redacted>: Unable to parse configuration of mojo org.codehaus.mojo:webstart-maven-plugin:1.0-beta-6:jnlp-inline for parameter pack200: Cannot find default setter in class org.codehaus.mojo.webstart.Pack200Config -> [Help 1]
The Help link goes to the following page.
https://cwiki.apache.org/confluence/display/MAVEN/PluginConfigurationException
As far as I can figure out, the webstart-pack200-impl dependency requires some configuration to define which setter is used. Any information regarding setters that I have found online seems to be a different issue from this. I can't figure out if there is a way to set a configuration for a dependency.
Or am I looking at this in a completely incorrect way?
Many thanks in advance
the error points to pack200 which was configured as <pack200>false</pack200>in older version of webstart plugin configuration.
This can be resolved by changing pack200 configuration to this instead (within <configuration> section of the plugin settings)
<pack200><enabled>false</enabled></pack200>
for more details please refer http://www.mojohaus.org/webstart/webstart-maven-plugin/upgrade.html section "Important changes since 1.0-beta-3"
