dpkg: error: parsing file '/var/lib/dpkg/status' near line 9941 package 'libcloog-isl4:amd64'

After wasting let's say one hour, this solved it for me :
'sudo mv /var/lib/dpkg/status-old /var/lib/dpkg/status'

Set up gradle to build with alternative java

I am using ubuntu 14.04 LTS

Having java 7 and 8 installed from oracle.

Using alternative and working with java 7 but one of my projects use java 8.

gradle build --version

returns that it works with java 7 -> since most of my projects use this version, i don't want to change this.

Solution: creating in the java 8 project, in the root directory, file named gradle.properties

inside it for example in my case :
org.gradle.java.home=/usr/lib/jvm/java-8-oracle/


this way, when you will do gradle build in this project, gradle will use this version instead of the one defined for him.


Hoped it helped,

NoClassDefFoundError: jersey/repackaged/com/google/common/collect/Maps

Hi,

I am working with spring 4.0.4 and jersey 2.7 and Gradle 1.11 suddelny out of nowhere i build and deployed to my tomcat 7 (latest release) and got the above error.
Worked to figure out what went wrong about an hour.
Than i saw that they released a new 2.8 lately, decided to try it - it worked +


Problem solved for me after upgrading from jersey 2.7 to 2.8
and adding this to my gradle dependencies
"org.glassfish.jersey.bundles.repackaged:jersey-guava:2.8"



Hopefully it will help you too,

How to expose spring ehcache 2.8.2 to jmx

In this version ehcache statistics is enabled by default.

I am using ehcache as spring cache.

it's easy

find the place where you define your config
like 'net.sf.ehcache.config.Configuration config = new net.sf.ehcache.config.Configuration()'

in my case i use annotations therefore i got this line in the code, in your case, maybe defined as bean inside the xml .

add the following :
      'config.setMonitoring(net.sf.ehcache.config.Configuration.Monitoring.ON.name());'

Yeah i wondered too why it's not possible to give the enum only .. maybe in the next version... '

Worked for me .
