I've done the following steps per the tika guide:
Add the tika-core and tika-parser dependencies to the pom.xml of the maven project
Run maven install from eclipse to produce tika-core jar and tika-parser jar
Add tika-core jar and tika-parser jar to my eclipse project build path
And I get this runtime exception when trying to run tika:
Exception in thread "main" java.lang.NoClassDefFoundError: org.apache.pdfbox.pdmodel.encryption.InvalidPasswordException

As far as I can see, when I build the jars using maven, it does add pdfbox properly... from the build log:
[INFO] Including org.apache.pdfbox:pdfbox:jar:2.0.1 in the shaded jar.
[INFO] Including org.apache.pdfbox:fontbox:jar:2.0.1 in the shaded jar.
[INFO] Including org.apache.pdfbox:pdfbox-tools:jar:2.0.1 in the shaded jar.
[INFO] Including org.apache.pdfbox:pdfbox-debugger:jar:2.0.1 in the shaded jar.
[INFO] Including org.apache.pdfbox:jempbox:jar:1.8.12 in the shaded jar.
And here are my maven dependencies:
<dependencies>
<!-- https://mvnrepository.com/artifact/org.apache.tika/tika-core -->
<dependency>
<groupId>org.apache.tika</groupId>
<artifactId>tika-core</artifactId>
<version>1.13</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.tika/tika-parsers -->
<dependency>
<groupId>org.apache.tika</groupId>
<artifactId>tika-parsers</artifactId>
<version>1.13</version>
</dependency>
</dependencies>
The problem is that if you manually add tika-core and tika-parsers jars in your build path you will not have the transitive dependencies that are listed in their own POM.
So I would suggest to:
Remove the tika-core and tika-parsers version that you have built yourself. Instead you should rely on the versions that are available on central. This will ensure that another one building your project will get the same jar (and not a locally built one)
You have two options
(Option A, use Maven) Do not add manually into Eclipse build path the jars. Rely either or built-in Maven plugin for Eclipse (m2e for instance) or use Eclipse plugin for maven (call mvn eclipse:eclipse to update .classpath and .project).
(Option B, without Maven) If you cannot use Maven for your project, you will have to add not only tika-parsers and tika-core jars, but all (most of) the transitive dependencies needed by these project (including for instance specific library per format [POI for Office, pdfbox for PDF...). You can get a list of the dependencies by typing mvn dependency:list in the folder containing the pom of tika-parsers.

When doing a mvn clean install -U I am getting:
[ERROR] Failed to execute goal on project xxx-security: Could not resolve dependencies for project xxx:xxx-security:jar:50-SNAPSHOT: Failed to collect dependencies at

dard/org/mybatis/mybatis/$%7Bmybatis.version%7D/mybatis-$%7Bmybatis.version%7D.pom. Return code is: 400 , ReasonPhrase:Invalid repository path. -> [Help 1]
What I don't get is why maven is using mybatis.version in the url to get the dependency rather than a version number. I have searched the code and cannot find mybatis.version in there. I did find:
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.0.4</version>
</dependency>
So why is maven using mybatis.version rather than 3.0.4?
It looks like your xxx:xxx-persistence:jar:50-SNAPSHOT jar has internal dependency with org.mybatis:mybatis:jar:${mybatis.version}. Provided that you define mybatis.version in your properties.
You can do following:
Execute mvn dependency:tree to check which specific jar has this dependency.
Also define <mybatis.version>3.0.4</mybatis.version> under <properties> section of pom.xml. You can optionally remove <version>3.0.4</version> from your <dependency> section where you defined mybatis dependency.
I am facing a problem with maven dependency.
I have a maven project called DdsInterface. Inside the pom.xml there is this dependency
...
<dependency>
<groupId>it.snam.ned</groupId>
<artifactId>ned-core</artifactId>
<version>0.0.1-SNAPSHOT</version>
<scope>compile</scope>
</dependency>
...
That is used in a class to import the NedRestTemplate object. Everything in the project is working.
Then I build a jar with command maven clean install and generate a ned-dds-interface.jar.
I then install the library in my local repository .m2 with command
mvn install:install-file -Dfile="target/ned-dds-interface.jar" -DgroupId=ned-dds-interface -DartifactId=ned-dds-interface -Dversion=1.2 -Dpackaging=jar
Now I want to use this library ned-dds-interface in another project call Portal. So in the pom.xml I created the dependency
<dependency>
<groupId>ned-dds-interface</groupId>
<artifactId>ned-dds-interface</artifactId>
<version>1.2</version>
<scope>compile</scope>
</dependency>
Finally I create the war for the project to run in a Web logic server using
mvn clean install
and then deploy the package Portal that successfully run on Weblogic. But executing a function I get the following error
Root cause of ServletException.
java.lang.NoClassDefFoundError: it/snam/ned/libs/core/NedRestTemplate

Can someone please help me with this problem?
Version: maven 3.6.3
I try to put this dependency into pom.xml,but it not auto download
<dependency>
<groupId>com.datastax.spark</groupId>
<artifactId>spark-cassandra-connector_2.11</artifactId>
<version>2.4.3</version>
</dependency>
so i use command line:
mvn dependency:get -DremoteRepositories=http://repo1.maven.org/maven2 -DgroupId=com.datastax.spark -DartifactId=spark-cassandra-connector_2.11 -Dversion=2.4.3 -Dtransitive=false
but it give me couldn't download artifact error log :
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.8:get (default-cli) on project standalone-pom: Couldn't download artifact: Could not transfer artifact com.datastax.spark:spark-cassandra-connector_2.11:jar:2.4.3
Do I need to upgrade remoteRepositories?
Why are some commonly used packages automatically downloaded quickly ? such as guava,commons-lang.
Some new versions are always problematic to rely on for download,Is it no cache in
repository?
How can I download the dependency? Thanks
My setup:
Sonarqube 5.1.1
Sonar-Maven Plugin 2.6 (also tried 2.7 and 3.6)
JDK 1.7.0_51
Example of the error:
16:00:54 [INFO] [23:00:54.219] Sensor JavaSquidSensor
16:00:55 [INFO] [23:00:55.030] Java Main Files AST scan...
16:00:55 [INFO] [23:00:55.030] 1532 source files to be analyzed
16:00:58 [ERROR] [23:00:57.927] Class not found: javax.annotation.Nullable
16:00:58 [ERROR] [23:00:57.928] Class not found: javax.annotation.CheckReturnValue
16:00:58 [ERROR] [23:00:58.114] Class not found: javax.annotation.Nullable
According to this stackoverflow question, javax.annotation should be part of java 1.7 and up. Furthermore, I've tried putting it in the local maven repository but that didnt help.
So where is Sonar trying to find this package? Any help?!?
Update:
I've tried modifying the sonar-maven-plugin to include a dependency on javax.annotation
I've tried putting the dependency in my maven's settings.xml
Upgrading my JDK to 1.8 has not helped.
According to http://docs.oracle.com/javase/7/docs/api/index.html?javax/annotation/package-summary.html the classes you expect are not part of JDK 7.
The classes you're looking for are part of google JSR-305 implementation that was initiated here https://code.google.com/p/jsr-305/source/browse/trunk/ri/src/main/java/javax/annotation/Nullable.java?r=24 and which moved to Findbugs:
<dependency>
<groupId>com.google.code.findbugs</groupId>
<artifactId>jsr305</artifactId>
<version>3.0.0</version>
</dependency>
According to https://jcp.org/en/jsr/detail?id=305 the JSR-305 is finished, but is in dormant status and has not been added to a JDK release yet.
Hope it helps.
To avoid adding SonarQube specific dependencies to your project, define a profile like this:
<profile>
<id>sonarqube</id>
<dependencies>
<dependency>
<groupId>org.joda</groupId>
<artifactId>joda-convert</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>com.google.code.findbugs</groupId>
<artifactId>jsr305</artifactId>
<version>3.0.0</version>
</dependency>
</dependencies>
</profile>
Then run your sonar analysis with a command like
mvn org.sonarsource.scanner.maven:sonar-maven-plugin:3.0.1:sonar -Psonarqube,sonarqube-dev
The sonarqube-dev profile is defined in my ~/.m2/settings.xml and it just specifies where my development environment SonarQube installation is
<profile>
<id>sonarqube-dev</id>
<properties>
<!-- no direct db connections in new sonar -->
<sonar.host.url>
http://localhost:9000/
</sonar.host.url>
</properties>
</profile>
What is achieved by all this?
sonarqube analysis specific dependencies don't pollute the project unnecessarily
no sonarqube maven plugin defined in pom.xml. Each developer and Jenkins can use whatever sonar plugin and server installation they wish
This is more an addendum to the latest answer:
I see similar problems and adding the google findbugs dependency to the project dependencies helps. Similar problems occured with joda convert like
[ERROR] [20:44:25.247] Class not found: org.joda.convert.ToString
Hence I also added
`<dependency>
<groupId>org.joda</groupId>
<artifactId>joda-convert</artifactId>
<version>1.8.1</version>
<scope>provided</scope>
</dependency>`
But note, that I set the scope to provided to prevent these new dependencies to be added to a resulting war file.
However, I still wonder why these errors occur since none of the analyzed classes seem to use these annotations?
I am using the maven-jspc-plugin in my pom.xml.
When i try to execute the jsp-compile goal (which executes the plugin) I get:
Caused by: java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
at org.apache.juli.logging.Slf4jLog.<init>(Slf4jLog.java:29)

I've tried downloading the (open) source for the maven-jspc-plugin and i am able to easily "mvn install" -- I don't get any build issues, however when i use that build in my project pom it still crashes and tells me it can't find LoggerFactory.
I've logged an issue with the Apache Sling project but am not making much headway.
https://issues.apache.org/jira/browse/SLING-2350
This link includes some more troubleshooting info as well as a simple maven project that uses the maven plugin. downloading the jspc-test.zip and "mvn install"ing will result in the error I've mentioned.
Also, i took a peak at the org.apache.juli pom.xml and it doesnt appear to list any dependencies at all.
Any thoughts on how to resolve would be appreciated.
Thanks!
Plugin dependencies are supplied in a different part of the POM:
<project>
<dependencies>
<!-- dependencies defined here don't get included for plugins -->
...
</dependencies>
<build>
<plugins>
<plugin>
.... jspc plugin section ....
<dependencies>
<dependency>
<!-- Try adding slf4j here --->
Though it does sounds like their POM is invalid if it doesn't already specify slf4j.
