Invalid LOC header Maven compilation error for Android support-v4
android, maven
Solution
That error means that the locally cached `.jar` is corrupt. Please delete `C:\Users\amrit.m2\repository\com\google\android\support-v4\r6\support-v4-r6.jar` and allow Maven to re-download the file.
If the error still occurs then the source repository where Maven is downloading the `.jar` from is bad. Consider switching Maven repositories or changing to a different version of the library - `r7` (if you can), for example:
<dependency>
<groupId>com.google.android</groupId>
<artifactId>support-v4</artifactId>
<version>r7</version>
</dependency>
Or manually downloading the `.jar` from a Maven repository like http://mvnrepository.com/artifact/com.google.android/support-v4/r6
Note: Google aren't responsible for adding those libraries to the Maven repositories, which is why a) they are not kept up to date and b) why (sometimes) they are corrupt - see Android support library setup with maven
Problem
I am getting compilation fail error while maven build my `pom.xml` file. Compilation error is: `error reading C:\Users\amrit\.m2\repository\com\google\android\support-v4\r6\support-v4-r6.jar; invalid LOC header (bad signature).` Does anyone know how to fix this problem? Below is my `pom.xml` file: ``` <project xmlns = "http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>MyListReq</groupId> <artifactId>MyListReq</artifactId> <version>0.0.1-SNAPSHOT</version> <name>AtosList</name> <dependencies> <dependency> <groupId>com.google.android</groupId> <artifactId>android</artifactId> <version>4.1.1.4</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.google.android</groupId> <artifactId>support-v4</artifactId> <version>r6</version> </dependency> </dependencies> <build> <sourceDirectory>src</sourceDirectory> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>3.1</version> <configuration> <source>1.6</source> <target>1.6</target> <fork>true</fork> <executable>C:\Program Files\Java\jdk1.7.0_03\bin\javac.exe </executable> </configuration> </plugin> <plugin> <groupId>com.jayway.maven.plugins.android.generation2</groupId> <artifactId>android-maven-plugin</artifactId> <configuration> <sdk> <path>${env.ANDROID_HOME}</path> <platform>17</platform> </sdk> </configuration> <extensions>true</extensions> </plugin> </plugins> </build> ``` I am not able to fix this problem. Any sort of help will be appreciated.
